Dual band sensitivity enhancements of a VO_x microbolometer array using a patterned gold black absorber (2016)

Infrared-absorbing gold black has been selectively patterned onto the active surfaces of a vanadium-oxide-based infrared bolometer array. Patterning by metal lift-off relies on protection of the fragile gold black with an evaporated oxide, which preserves much of gold black's high absorptance. This patterned gold black also survives the dry-etch removal of the sacrificial polyimide used to fabricate the air-bridge bolometers. For our fabricated devices, infrared responsivity is improved 22% in the long-wave IR and 70% in the mid-wave IR by the gold black coating, with no significant change in detector noise, using a 300°C blackbody and 80 Hz chopping rate. The increase in the time constant caused by the additional mass of gold black is ∼15%.
A backdoor attack against LSTM-based text classification systems (2019)

With the widespread use of deep learning system in many applications, the adversary has strong incentive to explore vulnerabilities of deep neural networks and manipulate them. Backdoor attacks against deep neural networks have been reported to be a new type of threat. In this attack, the adversary will inject backdoors into the model and then cause the misbehavior of the model through inputs including backdoor triggers. Existed research mainly focuses on backdoor attacks in image classification based on CNN, little attention has been paid to the backdoor attacks in RNN. In this paper, we implement a backdoor attack in text classification based on LSTM by data poisoning. When the backdoor is injected, the model will misclassify any text samples that contains a specific trigger sentence into the target category determined by the adversary. The existence of the backdoor trigger is stealthy and the backdoor injected has little impact on the performance of the model. We consider the backdoor attack in black-box setting where the adversary has no knowledge of model structures or training algorithms except for small amount of training data. We verify the attack through sentiment analysis on the dataset of IMDB movie reviews. The experimental results indicate that our attack can achieve around 95% success rate with 1% poisoning rate.
Deficiency of cyclic AMP-dependent protein kinases in human psoriasis. (1986)

To determine possible differences in the cyclic AMP-dependent protein kinases of normal and psoriatic human fibroblasts, the levels of the regulatory subunits (RI and RII, respectively) of protein kinase I and protein kinase II were quantitated by photoaffinity labeling with 8-azido[32P]cAMP. The level of RII was significantly decreased, or was undetectable, in cytosol prepared from fibroblasts from five psoriatic subjects when compared to RII levels found with normal human fibroblasts. The level of cytosolic RI was decreased in fibroblasts from four psoriatic patients and was within the normal range for one diseased patient when compared to RI levels in normal human fibroblasts. The elution profile from a DEAE-cellulose column of protein kinase activity in the soluble fraction from two psoriatic patients also showed a decrease in type I kinase activity and the complete absence of type II kinase activity. Other results indicate that the level of RI in erythrocyte membranes from psoriatic subjects is significantly decreased when compared to that of erythrocyte membranes from eight normal subjects. A significant correlation (P less than 0.001) was observed between the severity of the cutaneous manifestation of the disease and the level of RI in psoriatic erythrocyte membranes. The changes noted in the levels of RI and RII in cell types other than those thought to be specifically involved in the proliferative epidermis disorder of the disease suggest a general protein kinase deficiency.
Evaluation of antibody level against Fusobacterium nucleatum in the serological diagnosis of colorectal cancer (2016)

Fusobacterium nucleatum (F. nucleatum, Fn) is associated with the colorectal cancer (CRC). Fn-infection could induce significant levels of serum Fn-specific antibodies in human and mice. The objective of this study was to identify Fn-infection that elicit a humoral response in patients with CRC and evaluate the diagnostic performance of serum anti-Fn antibodies. In this work, we showed the mean absorbance value of anti-Fn-IgA and -IgG in the CRC group were significantly higher than those in the benign colon disease group and healthy control group (P < 0.001). The sensitivity and specificity of ELISA for the detection of anti-Fn-IgA were 36.43% and 92.71% based on the optimal cut-off. The combination of anti-Fn-IgA and carcino-embryonic antigen (CEA) was better for diagnosing CRC (Sen: 53.10%, Spe: 96.41%; AUC = 0.848). Furthermore, combining anti-Fn-IgA with CEA and carbohydrate antigen 19-9 (CA19-9) (Sen: 40.00%, Spe: 94.22%; AUC = 0.743) had the better ability to classify CRC patients with stages I-II. These results suggested that Fn-infection elicited high level of serum anti-Fn antibodies in CRC patients, and serum anti-Fn-IgA level may be a potential diagnosing biomarker for CRC. Serum anti-Fn-IgA in combination with CEA and CA19-9 increases the sensitivity of detecting early CRC.

Exploring the Use of Computer Based Exams for Undergraduate Accounting (2017)

This paper explores the use of computer-based exams (CBEs) for undergraduate accounting. The primary objective of writing this paper was to establish whether CBEs should be integrated with paper-based exams as a summative assessment in undergraduate accounting modules. Professional accounting organisations and universities and colleges in Ireland were contacted to establish whether CBEs had been adopted and, if so, to take relevant lessons from their experience. The literature reviewed the experiences of students, academics, institutions and professional accounting organisations using CBEs worldwide. Findings from this desk-based research indicated an overall positive experience with CBEs. The professional accounting organisations are continuing to adopt CBEs as a method of assessment, with one professional accounting organisation adopting CBEs for examinations across their entire syllabus. In contrast, four of nine third level institutions in Ireland use CBEs. CBEs are not unique to professional accounting organisations. The adoption of CBEs in undergraduate accounting is an area that needs further exploration. This will help determine best practice to facilitate students who wish to pursue a career in accountancy, and support completion of the professional accounting exams. An area for further research is to interview academics to hear their reasons for not adopting CBEs, and to survey the student experience of CBEs for post-undergraduate and post-professional accounting.

High-Speed Light Modulation in Avalanche Breakdown Mode for Si Diodes (2004)

The light emission process from a p-n junction in the forward-bias region is slow to respond to modulation signals due to the indirect band structure of silicon. Experimental results for a reverse-bias region showing light modulation in the range of tens of gigahertz are observed for the first time. For such a light emitter, the limiting speed of light modulation is shown to be determined by the transit time of the minority carriers across the junction during the filament formation of breakdown currents, which has been demonstrated by simulation of the propagation of a shockwave-like pattern in the breakdown field.
A reconfigurable, power-scalable rake receiver IP for W-CDMA (2003)

During the last years wireless market has experienced an exponential growth. 2G systems are essentially voice-oriented: the main innovation expected from 3G ones is the ubiquitous Internet and multimedia fruition. The transition from 2G to 3G provides both opportunities and challenges: one way to make this migration as smoother as possible relies on the employment of reconfigurable architectures. In this paper a reconfigurable Rake Receiver for W-CDMA is proposed. Very promising results from the physical implementation on a XCV300E have been obtained.
Laser ultrasonics for the evaluation of composites and coatings (1995)

Laser ultrasonics, an esoteric laboratory curiosity in the 1960s, is finding its niche in industry today. The technique has evolved concurrently with advances in electronics and optics to achieve recent breakthroughs Two applications will be presented here : rapid inspection of complex shaped composite structures and in-situ monitoring of a coating process in hostile environments. The ability to inspect complex shapes rapidly with in-process capability is a clear cost benefit for the NDT community, where nondestructive testing has long been viewed as an added cost. Complex shape composite structures are now common, particularly in the aircraft industry, and may be critically load bearing. The ability to inspect virtually any shape without immersion is becoming ever more important. The rapidly growing aircraft engine coating industry is moving toward higher temperature coatings and therefore more efficient engine operation. Control of the coating process will be cost effective and there simply is no other way to quantitatively assess the process at temperatures as high as 1,400 °C (2,552 °F). These examples serve to demonstrate how a deep understanding of a complex subject has led to timely practical applications.
PRESENT OPTICS OPTIONS FOR TEV COLLIDERS. (1986)

A practical approach for implementing TeV collider optics with high luminosities pounds approx. = 10/sup 33/ (cm/sup 2/ s)/sup -1/ but without large pinch effects is given using current alternatives. Characteristics are considered that constrain the optics and the types and orders of magnets required. A modified linac FoDo cell based on permanent magnet hybrid quadrupoles is discussed. Similarly, a demagnifying, permanent magnet telescopic system that allows variation of beta, eta and energy is suggested for the final focus. The basic cell for low emittance damping rings can also be constructed solely from permanent magnets. Small diameter, low permeability, high field permanent magnets have proven useful for injection and extraction lines and are also compatible with the large particle near the interaction regions as well as with exotic experiments for production and use of secondary beams or for multi-bunch coalescing schemes for control of longitudinal bunch distribution. An 8-10 GeV prototype cell and final focus experiment is proposed to verify and study such systems as well as do some interesting physics tests. One example, which could be used with the PEP storage ring, would convert an external electron beam into a photon beam to avoid beamstrahlung effects - a major problem for high energy e+- colliders.
BILE ACIDS IN XENOGENEIC EX-VIVO LIVER PERFUSION (2000)

Porcine livers perfused with human blood can clear the serum of potentially toxic human bile acids and excrete them into bile. Simultaneously, the percentage of pig-specific bile acids in patient serum increases during xenogeneic perfusion for unknown reasons. The relative hepatic uptake of bile acid from serum is similar to bile acid excretion in bile. Further development of systems using porcine livers or hepatocytes is warranted.
Trapping and aerogelation of nanoparticles in negative gravity hydrocarbon flames (2014)

We report the experimental realization of continuous carbon aerogel production using a flame aerosol reactor by operating it in negative gravity (−g; up-side-down configuration). Buoyancy opposes the fuel and air flow forces in −g, which eliminates convectional outflow of nanoparticles from the flame and traps them in a distinctive non-tipping, flicker-free, cylindrical flame body, where they grow to millimeter-size aerogel particles and gravitationally fall out. Computational fluid dynamics simulations show that a closed-loop recirculation zone is set up in −g flames, which reduces the time to gel for nanoparticles by ≈106 s, compared to positive gravity (upward rising) flames. Our results open up new possibilities of one-step gas-phase synthesis of a wide variety of aerogels on an industrial scale.
P-glycoprotein expression is increased in human secretory and gestational endometrium. (1991)

To determine the expression, distribution, and intracellular localization of the multi-drug resistance gene product P-glycoprotein (Pgp) in the human menstrual cycle and in early gestational endometrium, we retrospectively studied 36 endometrial samples utilizing 3 murine monoclonal antibodies (MAbs), MAb C219, MAb C494, and MAb JSB-1, which recognize spatially distinct cytoplasmic epitopes of Pgp. Formalin-fixed, paraffin-embedded endometrial samples obtained from 36 women of reproductive age with normal menstrual cycles were assigned morphologic menstrual dates: proliferative (N = 10), secretory (N = 19), menstrual (N = 1), and gestational endometrium (N = 6). The cellular localization, staining intensity, and percentage of Pgp immunoreactive cells varied with the phase of the menstrual cycle. Early proliferative endometria revealed no Pgp immunoreactivity for all three MAbs. Mid-proliferative endometria showed weak immunostaining in less than 15% of the glandular epithelia. Late proliferative endometria showed a strong apical paranuclear/Golgi staining pattern. Early secretory endometria showed strong luminal membranous, subnuclear vacuolar membranous, and supranuclear vacuolar membranous immunostaining to all 3 MAbs in greater than 80% of the glandular epithelia. Apical paranuclear/Golgi and membranous staining were present in nonvacuolated mid-secretory glands. Immunoreactivity diminished in the late secretory phase with mild to moderate staining in less than 35% of the endometrial glands. Menstrual endometria showed weak, focal staining. All gestational endometria showed marked cytoplasmic, membranous, and apical/Golgi immunostaining both in the hypersecretory (Arias-Stella) endometrial glands as well as in the decidua. In general, the intensity of MAb C494 immunostaining was weaker than that of MAb C219 or JSB-1. These results suggest the following: Pgp expression parallels that of nuclear progesterone receptor expression in the normal human endometrial cycle and early gestational endometrium; Pgp expression corresponds to rising plasma and tissue levels of progesterone as well as to morphologic changes in the endometrial glandular epithelium associated with the marked development of the secretory apparatus; Pgp expression is hormonally regulated and may be involved in uteroplacental transport of substrates important in the implantation process and in early embryo-endometrial interactions; and Pgp may be involved in the transport of progesterone across the uterine epithelium during pregnancy.
FADNet: A Fast and Accurate Network for Disparity Estimation (2020)

Deep neural networks (DNNs) have achieved great success in the area of computer vision. The disparity estimation problem tends to be addressed by DNNs which achieve much better prediction accuracy in stereo matching than traditional hand-crafted feature based methods. On one hand, however, the designed DNNs require significant memory and computation resources to accurately predict the disparity, especially for those 3D convolution based networks, which makes it difficult for deployment in real-time applications. On the other hand, existing computation-efficient networks lack expression capability in large-scale datasets so that they cannot make an accurate prediction in many scenarios. To this end, we propose an efficient and accurate deep network for disparity estimation named FADNet with three main features: 1) It exploits efficient 2D based correlation layers with stacked blocks to preserve fast computation; 2) It combines the residual structures to make the deeper model easier to learn; 3) It contains multi-scale predictions so as to exploit a multi-scale weight scheduling training technique to improve the accuracy. We conduct experiments to demonstrate the effectiveness of FADNet on two popular datasets, Scene Flow and KITTI 2015. Experimental results show that FADNet achieves state-of-the-art prediction accuracy, and runs at a significant order of magnitude faster speed than existing 3D models. The codes of FADNet are available at https://github.com/HKBU-HPML/FADNet.
Metacarpophalangeal joint implant arthroplasty with a Silastic spacer. (1984)

We evaluated Silastic implant arthroplasty in the metacarpophalangeal joints of rheumatoid patients by a prospective analysis of the cases of twenty-eight patients. One hundred and fifteen such implants were followed for an average of fifty-four months (range, twenty-four to 125 months). The postoperative active motion of the metacarpophalangeal joint averaged 43 degrees, from 13 degrees of extension to 56 degrees of flexion. The average range of active motion of the metacarpophalangeal joint increased 17 degrees over preoperative values. Ulnar drift recurred in forty-nine fingers (43 per cent), and fracture of the spacer occurred in twenty-four joints (21 per cent). The sites of three spacers became infected, and treatment required the amputation of one finger. Preoperative and postoperative key pinch and grip strengths were unchanged. Patient satisfaction was high; twenty patients (71 per cent) experienced significant pain relief, nineteen patients (68 per cent) felt that they had much better hand function, and twenty-three patients (82 per cent) thought that the cosmetic appearance of the hand was improved.

Wireless data encoding and decoding using OAM modes (2014)

A means of encoding and decoding data using wireless orbital angular momentum (OAM) modes is proposed and analysed. Source data symbols are used to select an OAM mode, which is generated using an 8‐element circular array. A 2‐element array is used to detect the mode by estimating the phase gradient of the received signal, and hence identifying the transmitted data symbol. The results are presented in terms of mode estimation error.
Molecular engineering of organic electroactive materials for redox flow batteries (2017)

With high scalability and independent control over energy and power, redox flow batteries (RFBs) stand out as an important large-scale energy storage system. However, the widespread application of conventional RFBs is limited by the uncompetitive performance, as well as the high cost and environmental concerns associated with the use of metal-based redox species. In consideration of advantageous features such as potentially low cost, vast molecular diversity, and highly tailorable properties, organic and organometallic molecules emerge as promising alternative electroactive species for building sustainable RFBs. This review presents a systematic molecular engineering scheme for designing these novel redox species. We provide detailed synthetic strategies for modifying the organic and organometallic redox species in terms of solubility, redox potential, and molecular size. Recent advances are then introduced covering the reaction mechanisms, specific functionalization methods, and electrochemical performances of redox species classified by their molecular structures. Finally, we conclude with an analysis of the current challenges and perspectives on future directions in this emerging research field.
Trojan-horse attacks on quantum-key-distribution systems (2006)

General Trojan-horse attacks on quantum-key-distribution systems, i.e., attacks on Alice or Bob's system via the quantum channel, are analyzed. We illustrate the power of such attacks with today's technology and conclude that all systems must implement active counter measures. In particular, all systems must include an auxiliary detector that monitors any incoming light. We show that such counter measures can be efficient, provided that enough additional privacy amplification is applied to the data. We present a practical way to reduce the maximal information gain that an adversary can gain using Trojan-horse attacks. This does reduce the security analysis of the two-way plug-and-play implementation to those of the standard one-way systems.
Adhesive properties of soy proteins modified by sodium dodecyl sulfate and sodium dodecylbenzene sulfonate (2000)

Abstract A study was conducted on adhesive and water‐resistance properties of soy protein isolates modified by sodium dodecyl sulfate (SDS) (0.5, 1, and 3%) and sodium dodecylbenzene sulfonate (SDBS) (0.5, 1, and 3%) and applied on walnut, cherry, and pine plywoods. Soy proteins modified by 0.5 and 1% SDS showed greater shear strengths than did unmodified protein. One percent SDS modification had the highest shear strength within each wood type tested. Soy proteins modified with 0.5 and 1% SDBS also showed greater shear strengths than did the unmodified protein. The 1% SDBS‐modified soy protein had the highest shear strength in all wood samples tested. Compared to the unmodified protein, the modified proteins also exhibited higher shear strengths after incubation with two cycles of alternating relative humidity and zero delamination rate and higher remaining shear strengths after three cycles of water soaking and drying. These results indicate that soy proteins modified with SDS and SDBS have enhanced water resistance as well as adhesive strength. Possible mechanisms for the effects of SDS and SDBS also are discussed.
