An Algebra for Access Control (2011)

This dissertation describes an algebraic framework for automatic construction of mathematical models of programs executing on access-control computer systems. The algebraic model of any program overapproximates the possible behaviors of the program. This dissertation proves that the model can be constructed in polynomial time. The model of a program can be used to define an optimal access control policy for the program, or to evaluate existing policies. Furthermore, this dissertation proves a consistency theorem that characterizes those access-control policies that restrict access to functions and that exhibit corresponding access-control policies restricting access to the data manipulated by those functions. The types of access control to which the model is applied are Role-Based Access Control (RBAC) and Stack-Based Access Control (SBAC).
Fabrication of two-layer microphotonic structures without planarization (2005)

A novel nanofabrication scheme for two-layer microphotonic structures were proposed and applied to the fabrication of integrated, mode-evolution-based polarization splitters and rotators. Prototype devices demonstrated effective splitting and rotating of polarization with low cross-talk.

300-GHz-band wireless communication using a low phase noise photonic source (2019)

The implementation of advanced multi-level modulation schemes such as quadrature phase-shift keying (QPSK) in contrast to the conventional on-off keying (OOK) is crucial to further boost the terahertz (THz) communications speed. Thereby, the phase noise reduction in the THz range is one of the key goals that need to be urgently achieved. In this paper, a low phase-noise photonic source based on the stimulated Brillouin scattering (SBS) phenomenon is first introduced in a 300-GHzband QPSK wireless communication link. The highest data rate at forward-error-correction limited condition was 15 Gbaud with the SBS source, and transmission characteristics are evaluated and compared with conventional optical frequency comb (OFCG)based sources at 5 Gbaud. Our Brillouin-based photonic source has been proven to offer better performances than the OFCG-based one with respect to the phase noise, the optical carrier to noise ratio, and the bit error rate in communications.
Autonomic Regulation of Myocardial Contractility* (2020)

The autonomic nervous system thus modifies cardiac performance by means of interaction of catechols or acetylcholine with discrete receptor proteins, located in the sarcolemma of cardiac cells. The effects of increased cardiac autonomic activity are markedly asymmetrical. While the right sympathetic cardiac nerves directly control sinoatrial performance, the left sympathetics are more prominent in regulation of ventricular contractile force. The inhibitory effects of vagal activity on atrial contractility were clearly demonstrated by R. A. Gesell and C. J. Wiggers. The effects of increased cardiac autonomic activity are markedly asymmetrical. While the right sympathetic cardiac nerves directly control sinoatrial performance, the left sympathetics are more prominent in regulation of ventricular contractile force. When heart rate and other factors that modify myocardial contractility are maintained constant, increased traffic in the sympathetic cardiac nerves elicits predictable augmentation in myocardial contractility. The degree of synchronicity with which myocardial fibers contract is critical to the ability of cardiac ejection to meet demands for increased output.
Malignant melanoma of the ileo-anal pouch anastomosis after restorative proctocolectomy for ulcerative colitis: report of a case (2013)

A 62 year-old patient with therapy-refractory pouchitis after proctocolectomy for ulcerative colitis was admitted with hematochezia and abdominal discomfort. A malignant melanoma (MM) was found after repeated biopsies of the pouch. Complete staging revealed no evidence for distant metastases and the patient underwent abdominoperineal pouch resection. Six weeks later, the patient was readmitted because of severe general deterioration and diffuse metastatic spread to the liver was found. The patient died of hepatorenal syndrome shortly thereafter.Patients with inflammatory bowel disease are at increased risk of developing cancer, including rarities such as MM. Our experience stresses the importance of repeated biopsies in therapy-refractory pouchitis.
A COMPUTER-BASED ADAPTIVE ASSOCIATIVE MEMORY IN SUPPORT OF DESIGN AND PLANNING (1991)

In this paper, we report on continuing research on the organization and functionalities of a certain type of computer-implemented associative memory. The associative memory in question is being created to serve as part of a feature-based design system, at present to be used primarily in suDwrt o f the design, fabrication planning, or inspection planning of discrete mechanical machine parts. This present effort is consonant with prior related work in the realm of case-based reasoning, especially as related to the role of memory in design. Our associative memory innovations are in the use of fuzzy sets and neural net computing in the representation, storage and retrieval of design, fabrication, inspection and materials knowledge. We have designed and implemented a considerable portion of the associative memory and have demonstrated retrieval of previous designs on the basis of qualitative geometry. We have also demonstrated ability to explore materials composition with the objective of meeting critical materials properties constraints. Acknowle&ement
Steroid sulfatase inhibitors (2003)

Steroid sulfatase (STS) regulates the local production of oestrogens and androgens from systemic precursors in several tissues. It catalyses the hydrolysis of the sulfate esters of 3-hydroxy steroids, which are inactive transport or precursor forms of the active 3-hydroxy steroids. In recent years, this enzyme has received considerable attention due to its potential involvement in the pathogenesis of a number of diseases. Inhibitors of STS are considered to be potential new therapeutic agents for the treatment of oestrogen- and androgen-dependent disorders. Indications range from cancers of the breast, endometrium and prostate to androgenic alopecia and acne. In addition, STS inhibitors are proposed to have positive effects on cognitive dysfunction. This review summarises the patents on STS inhibitors that have appeared since 1999, putting them in the context of relevant publications. Earlier patents were covered by a previous review by Poirier, Ciobanu and Maltais in this journal.
Origins of oblique‐slip faulting during caldera subsidence (2013)

Abstract Although conventionally described as purely dip‐slip, faults at caldera volcanoes may have a strike‐slip displacement component. Examples occur in the calderas of Olympus Mons (Mars), Miyakejima (Japan), and Dolomieu (La Reunion). To investigate this phenomenon, we use numerical and analog simulations of caldera subsidence caused by magma reservoir deflation. The numerical models constrain mechanical causes of oblique‐slip faulting from the three‐dimensional stress field in the initial elastic phase of subsidence. The analog experiments directly characterize the development of oblique‐slip faulting, especially in the later, non‐elastic phases of subsidence. The combined results of both approaches can account for the orientation, mode, and location of oblique‐slip faulting at natural calderas. Kinematically, oblique‐slip faulting originates to resolve the following: (1) horizontal components of displacement that are directed radially toward the caldera center and (2) horizontal translation arising from off‐centered or “asymmetric” subsidence. We informally call these two origins the “camera iris” and “sliding trapdoor” effects, respectively. Our findings emphasize the fundamentally three‐dimensional nature of deformation during caldera subsidence. They hence provide an improved basis for analyzing structural, geodetic, and geophysical data from calderas, as well as analogous systems, such as mines and producing hydrocarbon reservoirs.
Optically and Electrically Pumped GaN-based VCSELs (2007)

We report the recent progress of GaN-based VCSELs with a hybrid cavity structure comprised an epitaxial AIN/GaN DBR with superlattice insertion layers, an InGaN/GaN MQW active region and a top dielectric DBR. The lasers achieved laser action under optical pumping at the room temperature with a narrow linewidth. The preliminary results of the electrically pumped VCSEL will also be presented.
Whistleblowing (2022)

Abstract This book has been substantially updated since the previous edition, reflecting major case law developments. Chapter 1 introduces the work and considers significant proposals for reform and the new EU Whistleblowing Directive. Part 1 then sets out the statutory framework for the protection of whistleblowers under the Employment Rights Act. Chapter 2 sets out the structure of the UK legislation, and principles of construction, as a matter of domestic law. Chapter 3 describes the interface between whistleblowing protection and the interpretive requirement to conform with the European Convention on Human Rights (Chapter 3). There are two chapters. The first, on extra-territoriality (Chapter 8), covers material previously included within what is now Chapter 7 but also includes consideration of the position post-Brexit. The second addresses the important considerations which arise in relation to privilege and judicial immunity (Chapter 14). Part 2 (Chapters 15 to 20) deals with whistleblowing-related issues beyond the specific legislative scheme and also, in Chapter 17, section 43J ERA which makes void and provision in an agreement with a worker which would preclude protected disclosure. The final part of the book considers practical aspects of whistleblowing protection. Chapter 21 considers significant developments on the approach to this in the Health and Financial Services sectors, including the new provisions in the ERA prohibiting discrimination on the ground of protected disclosures against NHS applicants (and though not yet in force applicants in Children Social Care). Chapter 22 then considers whistleblowing policies more broadly, and the interface with data protection requirements. Finally, the Appendices include an illustrative case study, a survey of awards in relation to injury to feelings and aggregated damages (to be read with Chapter 12 on Remedies), and precedents relevant to whistleblowing claims.

Integration of low loss vertical slot waveguides on SOI photonic platforms for high efficiency carrier accumulation modulators (2020)

Silicon accumulation type modulators offer prospects of high power efficiency, large bandwidth and high voltage phase linearity making them promising candidates for a number of advanced electro-optic applications. A significant challenge in the realisation of such a modulator is the fabrication of the passive waveguide structure which requires a thin dielectric layer to be positioned within the waveguide, i.e. slotted waveguides. Simultaneously, the fabricated slotted waveguide should be integrated with conventional rib waveguides with negligible optical transition losses. Here, successful integration of polysilicon and silicon slot waveguides enabling a low propagation loss 0.4-1.2 dB/mm together with an ultra-small optical mode conversion loss 0.04 dB between rib and slot waveguides is demonstrated. These fabricated slot waveguide with dielectric thermal SiO<sub>2</sub> layer thicknesses around 6 nm, 8 nm and 10 nm have been characterized under transmission electron microscopy allowing for strong carrier accumulation effects for MOS-capacitor electro-optic modulators.
Coexistence of enhanced mobile broadband communications and ultra reliable low latency communications in mobile front-haul (2018)

5G systems are supposed to support coexistence of multiple services such as ultra reliable low latency communications (URLLC) and enhanced mobile broadband (eMBB) communications. The target of eMBB communications is to meet the high-throughput requirement while URLLC are used for some high priority services. Due to the sporadic nature and low latency requirement, URLLC transmission may pre-empt the resource of eMBB transmission. Our work is to analyze the URLLC impact on eMBB transmission in mobile front-haul. Then, some solutions are proposed to guarantee the reliability/latency requirements for URLLC services and minimize the impact to eMBB services at the same time.
Performance of switched mode AC power supply (2002)

In order to enhance the injection performance, the AC power supplies of the booster synchrotron of SRRC must output high quality current waveform. To ensure smooth and efficient injection of the booster ring, the phase jitter of the AC power supplies current must be small than +/-4ns. A new AC power supplies are constructed and employ IGBT modules operating at higher switching frequency than the old GTO-based system. This will not only improve the phase jitter produced but also increase the operating efficiency of the power supplies. The measured dynamic range of the 10 Hz sine wave current output of the new AC power supplies is better than 75dB; and phase jitter is less than +/-4ns. The improved performance is illustrated in the paper.

Endoscopic versus Laparoscopic Full-Thickness Biopsy in the Pathological Evaluation of the Enteric Nervous System (2018)

A full-thickness biopsy of the bowel wall is required to evaluate the enteric nervous system. A patient with aggravating gastrointestinal symptoms underwent a laparoscopic full-thickness biopsy of the ileum and, 1 year later, an endoscopic full-thickness biopsy of the sigmoid colon. Both samples showed enteric neuropathy characterized by vacuolated and enlarged neurons. The length of the myenteric plexus was greater in the endoscopic (23 mm) compared to the laparoscopic (11 mm) biopsy, with fewer tissue artefacts in the endoscopic approach [corrected]. Clinical deterioration was paralleled by enteric neuropathy with an increase in the percentage of vacuolated and enlarged enteric neurons from 24 to 35%.
Modifications of Well-Defined Polysilanes (1989)

Different homo- and copolysilanes were prepared by sonochemical reductive coupling of disubstituted dichlorosilanes with sodium. Polymers formed in the presence of ultrasound were monomodal, with polydispersities (ratio of weight-average molecular weight to number-average molecular weight, Mw/Mn) as low as <1.2. Polysilanes that contain aryl groups were dearylated upon treatment with strong protonic acids such as trifluoromethanesulfonic (triflic) acid. The resulting triflated polysilanes reacted readily with different nucleophiles to yield alkoxy- and amino-substituted polysilanes. Triflated polymers reacted with monomers that could be polymerized cationically to form graft copolymers.

High Yield Poly(ethylene-alt-maleic acid) Grafting to Wood Pulp while Minimizing Fiber/Fiber Wet Adhesion (2021)

Heating bleached kraft pulps treated with poly(ethylene-<i>alt</i>-maleic acid) (PEMAc) can lead to high yields of carboxylated polymer grafted to fibers. However, in many cases, the cured, dry pulp cannot be effectively repulped (redispersed in water) because the wet strength is too high. Impregnation with PEMAc solutions at pH 4 followed by high temperature (120-180 °C), catalyst-free curing for short times can give fixation yields >85% while maintaining repulpability. The combination of high fixation yields with low wet strength is possible because the extent of curing required for high grafting yields is less than the curing requirement for high wet strength. Two challenges in moving this technology to practicable applications are (1) identifying the optimum laboratory pulp curing conditions and (2) translating laboratory curing conditions to industrial processes. A modeling tool was developed to meet these challenges. The model is based on the observation that for curing conditions giving high fixation yields the wet tensile indices of grafted pulp sheets showed a power-law dependence on the βΓ product where β is the conversion of the succinic acid moieties in PEMAc to the corresponding succinic anhydride groups in the curing step and Γ is the amount of polymer applied to the pulp. For two PEMAc molecular weights and two pulp types, the power-law slopes were 0.6; however, the pre-exponential terms depended upon the specific polymer and pulp type combination. We propose that the relationships between the wet tensile index and βΓ, from polymer-treated, laboratory pulp handsheets, can be used to predict if proposed curing conditions for larger-scale processes will produce a repulpable product.
Fluorous Mixture Synthesis of Four Stereoisomers of the C21-C40 Fragment of Tetrafibricin (2010)

Four stereoisomers of the C21-C40 fragment are synthesized in a single exercise with the aid of fluorous tagging to encode configurations at C37 and C33. After demixing and detagging, the isomers were found to have substantially identical (1)H NMR spectra. However, there were some small but reliable differences in their (13)C NMR spectra.
Designing a Color Filter with High Overall Transmittance for Improving the Color Accuracy of Digital Cameras (2021)

Previously improved color accuracy of a given digital camera was achieved by carefully designing the spectral transmittance of a color filter to be placed in front of the camera. Specifically, the filter is designed in a way that the spectral sensitivities of the camera after filtering are approximately linearly related to the color matching functions (or tristimulus values) of the human visual system. To avoid filters that absorbed too much light, the optimization could incorporate a minimum per wavelength transmittance constraint. In this paper, we change the optimization so that the overall filter transmittance is bounded, i.e. we solve for the filter that (for a uniform white light) transmits (say) 50% of the light. Experiments demonstrate that these filters continue to solve the color correction problem (they make cameras much more colorimetric). Significantly, the optimal filters by restraining the average transmittance can deliver a further 10% improvement in terms of color accuracy compared to the prior art of bounding the low transmittance.
Cardiac sympathetic afferent stimulation induces salt-sensitive sympathoexcitation through hypothalamic epithelial Na+ channel activation (2014)

The cardiac sympathetic afferent (CSA), which plays an important role in heart-brain communication for sympathoexcitation, is stimulated in heart failure. Additionally, high salt intake leads to further sympathoexcitation due to activation of hypothalamic epithelial Na + channels (ENaCs) in heart failure. In the present study, we stimulated the CSA in adult male mice by epicardial application of capsaicin and using ethanol as a control to determine whether CSA stimulation led to activation of hypothalamic ENaCs, resulting in salt-induced sympathoexcitation. Three days after capsaicin treatment, an upregulation of hypothalamic α-ENaCs, without activation of mineralocorticoid receptors, was observed. We also examined expression levels of the known ENaC activator TNF-α. Hypothalamic TNF-α increased in capsaicin-treated mice, whereas intracerebroventricular infusion of the TNF-α blocker etanercept prevented capsaicin-induced upregulation of α-ENaCs. To examine brain arterial pressure (AP) sensitivity toward Na + , we performed an intracerebroventricular infusion of high Na + -containing (0.2 M) artificial cerebrospinal fluid. AP and heart rate were significantly increased in capsaicin-treated mice compared with control mice. CSA stimulation also caused excitatory responses with high salt intake. Compared with a regular salt diet, the high-salt diet augmented AP, heart rate, and 24-h urinary norepinephrine excretion, which is an indirect marker of sympathetic activity with mineralocorticoid receptor activation, in capsaicin-treated mice but not in ethanol-treated mice. Treatment with etanercept or the ENaC blocker benzamil prevented these salt-induced excitatory responses. In summary, we show that CSA stimulation leads to an upregulation of hypothalamic α-ENaCs mediated via an increase in TNF-α and results in increased salt sensitivity.
