<title>Time-multiplexed color autostereoscopic display</title> (1996)

A practical color autostereoscopic display has been developed at Cambridge, and has been in operation since 1994. It provides six view directions at half VGA resolution (640 X 240 pixels) of 24-bit color at a luminance of 100 cd/m<SUP>2</SUP>. Each individual view direction is refreshed at standard television rates, so the display is capable of full motion animation or live 3D video. Versions with both 10 and 25 inch screen diagonal have been built. This paper describes the principles of the display, its development from an earlier monochrome version, the results of this development work, and ideas for future research. The original monochrome display, developed at Cambridge, has been in use since late 1991. It provides eight views at full VGA resolution or sixteen views at half VGA resolution. A series of views of a scene are displayed sequentially and an optical directional modulator, constructed from a liquid crystal shutting element, is synchronized with the image repetition rate to direct each image to a different zone in front of the display. The viewer's eyes thus see two different images and the head can be moved from side to side to look around objects, giving an autostereoscopic display with correct movement parallax. The use of a CRT makes for a flexible system where resolution and number of views can be easily varied. Development of the color display from the monochrome version was achieved by a color sequential system using a liquid crystal color shutter. As each view direction had to be displayed three times for the three primary colors, the maximum number of view directions was decreased to six. Full color (24-bit) images have been displayed on these six view autostereoscopic displays from a number of sources: computer generated images, digitized photographs, and live color video from a multiplexed camera also designed at Cambridge.

Fast Neutron Imaging with Semiconductor Nanocrystal Scintillators (2021)

Fast neutrons offer\nhigh penetration capabilities for both light\nand dense materials due to their comparatively low interaction cross\nsections, making them ideal for the imaging of large-scale objects\nsuch as large fossils or as-built plane turbines, for which X-rays\nor thermal neutrons do not provide sufficient penetration. However,\ninefficient fast neutron detection limits widespread application of\nthis technique. Traditional phosphors such as ZnS:Cu embedded in plastics\nare utilized as scintillators in recoil proton detectors for fast\nneutron imaging. However, these scintillation plates exhibit significant\nlight scattering due to the plastic–phosphor interface along\nwith long-lived afterglow (on the order of minutes), and therefore\nalternative solutions are needed to increase the availability of this\ntechnique. Here, we utilize colloidal nanocrystals (NCs) in hydrogen-dense\nsolvents for fast neutron imaging through the detection of recoil\nprotons generated by neutron scattering, demonstrating the efficacy\nof nanomaterials as scintillators in this detection scheme. The light\nyield, spatial resolution, and neutron-vs-gamma sensitivity of several\nchalcogenide (CdSe and CuInS&lt;sub&gt;2&lt;/sub&gt;)-based and perovskite halide-based\nNCs are determined, with only a short-lived afterglow (below the order\nof seconds) observed for all of these NCs. FAPbBr&lt;sub&gt;3&lt;/sub&gt; NCs\nexhibit the brightest total light output at 19.3% of the commercial\nZnS:Cu­(PP) standard, while CsPbBrCl&lt;sub&gt;2&lt;/sub&gt;:Mn NCs offer the best\nspatial resolution at ∼2.6 mm. Colloidal NCs showed significantly\nlower gamma sensitivity than ZnS:Cu; for example, 79% of the FAPbBr&lt;sub&gt;3&lt;/sub&gt; light yield results from neutron-induced radioluminescence\nand hence the neutron-specific light yield of FAPbBr&lt;sub&gt;3&lt;/sub&gt; is\n30.4% of that of ZnS:Cu­(PP). Concentration and thickness-dependent\nmeasurements highlight the importance of increasing concentrations\nand reducing self-absorption, yielding design principles to optimize\nand foster an era of NC-based scintillators for fast neutron imaging.
The crystal structure of tetradecanamide (1955)

Tetradecanamide, NI-I~.CO(CH2)12CH~, crystallizes in the monoclinic system with a 0 ----9-830.03, b 0 = 5.610.03, c o ----27-980.03 /~, fl ----95.10.5 , and space group P21/a. The unit cell conrains 4 molecules. The structure has been determined by means of two-dimensional projections. The molecules were found to occur in the crystal as dimers, packed into rows extending in the b direction, with the paraffin chains inclined to 46 40' from the b axis. The paraffin chains of adjacent rows are oppositely inclined, forming a crossed-chain structure.
Systematic evaluation of genetic mutations in ALS: a population-based study (2022)

Our results suggest that, because of its high diagnostic yield and increasingly competitive costs, along with the possibility of retrospectively reassessing newly described genes, WGS should be considered as standard genetic testing for all ALS patients. Additionally, our results provide a detailed picture of the genetic basis of ALS in the general population.

Broadband high-order mode pass filter based on mode conversion (2017)

We report a unique concept to implement a high-order mode pass filter using mode converters. Our proposed design method implements a high-order mode pass filter of any order, uses different mode converters available, and applies to a variety of planar lightwave circuit material platforms. We fabricate a broadband fundamental mode filter device using a Mach-Zehnder interferometer and Y-junctions to demonstrate our idea. The performance of the fabricated device is demonstrated experimentally in the wavelength range of 1.530-1.565 μm (C-band). This filter exhibits a simulated extinction ratio of 37 dB with an excess loss of 0.52 dB for the first-order mode transmission.

Clustering using a coarse-grained parallel genetic algorithm: a preliminary study (2002)

Genetic algorithms (GA) are useful in solving complex optimization problems. By posing pattern clustering as an optimization problem, GAs can be used to obtain optimal minimum squared error partitions. In order to improve the total execution time, a distributed algorithm has been developed using the divide and conquer approach. Using a standard communication library called PVM, the distributed algorithm has been implemented on a workstation cluster: the GA approach gives better quality clusters for many data sets compared to a standard K-means clustering algorithm. We have achieved a near linear speedup for the distributed implementation.
B2B contract implementation using windows DNS (2001)

This paper describes our implementation of a support infrastructure for electronic contracting --- an important ingredient of Business-to-Business (B2B) e-commerce. The paper first explains the main benefits of the new generation of Microsoft technologies - Windows Distributed interNet Applications Architecture (DNA) and BizTalk. This is followed by a detailed description of how we take advantage of the XML tools provided by these technologies - to implement our enterprise model of contracts. We use a real-world contract scenario as a test-bed for examining our e-contract architecture and for implementing our prototype. The prototype was developed using publicly available BizTalk preview technology.
HLA degenerate T‐cell epitopes from Plasmodium falciparum liver stage‐specific antigen 1 (LSA‐1) are highly conserved in isolates from geographically distinct areas (2000)

Considerable effort is directed at the development of a malaria vaccine that elicits antigen-specific T-cell responses against pre-erythrocytic antigens of Plasmodium falciparum. Genetic restriction of host T-cell responses and polymorphism of target epitopes on parasite antigens pose obstacles to the development of such a vaccine. Liver stage-specific antigen-1 (LSA-1) is a prime candidate vaccine antigen and five T-cell epitopes that are degenerately restricted by HLA molecules common in most populations have been identified on LSA-1. To define the extent of polymorphism within these T-cell epitopes, the N-terminal non-repetitive region of the LSA-1 gene from Malaysian P. falciparum field isolates was sequenced and compared with data of isolates from Brazil, Kenya and Papua New Guinea. Three of the T-cell epitopes were completely conserved while the remaining two were highly conserved in the isolates examined. Our findings underscore the potential of including these HLA-degenerate T-cell epitopes of LSA-1 in a subunit vaccine.

Extraction of Proteins with Aqueous Two-Phase Systems Formed by Protic Ionic Liquids and Inorganic Salts (2021)

A protein extraction and separation has been reported using the ionic liquid (IL)-based aqueous two-phase system (ATPS). Although ILs have many benefits, there was a problem of unfavorable physical properties such as high viscosity, or high-cost production of ILs. Recently protic ionic liquids (PILs) are emerging as an alternative to conventional ionic liquids. PILs are easily produced through a reaction between Brønsted acid and base at a relatively low cost. In this study, PILs (pyrrolidinium formate [Pyrr][HCOO] and propionate [Pyrr][C2H5COO] and inorganic salts (K3PO4, K2HPO4) as phase-forming constituents of ATPS, were used for the protein extraction.
Hydrogen Adsorption in Ultramicroporous Metal-organic Frameworks Possessing Silent Open Metal Sites (2023)

Herein, we report the use of an ultramicroporous (pore size <0.7 nm) metal-organic framework (MOF), [Ni3(pzdc)2(ade)2(H2O)4]2.18H2O (H3pzdc: pyrazole-3,5-dicarboxylic acid, ade: adenine), for hydrogen (H2) adsorption. Upon activation, [Ni3(pzdc)2(ade)2] was generated, and in situ carbon monoxide loading transmission infrared spectroscopy revealed that open Ni(II) sites could be generated. The MOF displayed a Brunauer-Emmett-Teller (BET) surface area of 160 m2/g. Hydrogen adsorption collected on this MOF at 77 K revealed a steep uptake at low pressure, and H2 uptake saturation was achieved at 0.15 bar. The affinity of this MOF for H2 is 9.7 1.0 kJ/mol. An interplay of in situ H2 loading experiments and computations confirmed that H2 does not bind to the open Ni(II) sites of the MOF, and the observed high affinity of the MOF for H2 is mainly attributed to its narrow pore size. To shed light on the impact of ultramicropores on H2 uptake, we experimentally compared the H2 uptake per surface area unit as a function of the pore size of other ultramicroporous, microporous, and mesoporous MOFs. Our results showcase that ultramicropores contribute the most to H2 uptake, and the size, shape, and functionality of our MOF are ideal and can be used as guiding principles for the design and synthesis of novel adsorbents for efficient H2 storage and delivery.
Entities as Experts: Sparse Memory Access with Entity Supervision (2020)

We focus on the problem of capturing declarative knowledge about entities in the learned parameters of a language model. We introduce a new model-Entities as Experts (EAE)that can access distinct memories of the entities mentioned in a piece of text. Unlike previous efforts to integrate entity knowledge into sequence models, EAE's entity representations are learned directly from text. We show that EAE's learned representations capture sufficient knowledge to answer TriviaQA questions such as "Which Dr. Who villain has been played by Roger Delgado, Anthony Ainley, Eric Roberts?", outperforming an encodergenerator Transformer model with 10 the parameters. According to the LAMA knowledge probes, EAE contains more factual knowledge than a similarly sized BERT, as well as previous approaches that integrate external sources of entity knowledge. Because EAE associates parameters with specific entities, it only needs to access a fraction of its parameters at inference time, and we show that the correct identification and representation of entities is essential to EAE's performance.
Synthesis of water-soluble surfactants using catalysed condensation polymerisation in green reaction media (2021)

Sustainable and biobased surfactants are required for a wide range of everyday applications. Key drivers are cost, activity and efficiency of production. Polycondensation is an excellent route to build surfactant chains from bio-sourced monomers, but this typically requires high processing temperatures (≥200 °C) to remove the condensate and to lower viscosity of the polymer melt. In addition, high temperatures also increase the degree of branching and cause discolouration through the degradation of sensitive co-initiators and monomers. Here we report the synthesis of novel surface-active polymers from temperature sensitive renewable building blocks such as dicarboxylic acids, polyols (d-sorbitol) and fatty acids. We demonstrate that the products have the potential to be key components in renewable surfactant design, but only if the syntheses are optimised to ensure linear chains with hydrophilic character. The choice of catalyst is key to this control and we have assessed three different approaches. Additionally, we also demonstrate that use of supercritical carbon dioxide (scCO<sub>2</sub>) can dramatically improve conversion by reducing reaction viscosity, lowering reaction temperature, and driving condensate removal. We also evaluate the performance of the new biobased surfactants, focussing upon surface tension, and critical micelle concentration.

Multi-Scale Carbon (Micro/Nano) Fiber Reinforcement of Polyetheretherketone Using High Shear Melt-Processing (2017)

Fiber-reinforced polymer matrix composites offer lightweight, high mechanical performance but have required much effort to achieve good fiber–matrix adhesion and uniform distribution, and generally suffer from low impact resistance. In this work, a uniform, high shear melt-processing method was used to prepare carbon fiber (CF) reinforced polyetheretherketone (PEEK), carbon nanofiber (CNF) reinforced PEEK, and multi-scale CF and CNF reinforced PEEK composites. Scanning electron microscopy images show good fiber distribution and fiber–matrix interaction, as well as surface crystallization of PEEK from the fiber surfaces. Tensile modulus and strength increase most significantly with the addition of CF but with a loss in ductility. The multi-scale composite of CF–CNF-PEEK displays the stiffening effect from the CF and retains more ductility due to the CNF. Further, the CF–CNF-PEEK composite displays the highest impact energy absorption. This study shows that good mixing of CFs and CNFs is achievable in PEEK using a uniform, high shear processing method that can easily produce intricate shapes and provides a stiff, high impact energy absorption multi-scale carbon fiber-reinforced composite.
3-D live (2002)

We describe a real-time 3-D augmented reality video- conferencing system. With this technology, an observer sees the real world from his viewpoint, but modified so that the image of a remote collaborator is rendered into the scene. We register the image of the collaborator with the world by estimating the 3-D transformation between the camera and a fiducial marker. We describe a novel shape- from-silhouette algorithm, which generates the appropriate view of the collaborator and the associated depth map at 30 fps. When this view is superimposed upon the real world, it gives the strong impression that the collaborator is a real part of the scene. We also demonstrate interaction in virtual environments with a live fully 3-D collaborator. Finally, we consider interaction between users in the real world and collaborators in a virtual space, using a tangible AR interface.
Characterization of Bacillus phage-K2 isolated from chungkookjang, a fermented soybean foodstuff (2010)

An investigation of a virulent Bacillus phage-K2 (named Bp-K2) isolated from chungkookjang (a fermented soybean foodstuff) was made. Bp-K2 differed in infectivity against a number of Bacillus subtilis strains including starter strains of chungkookjang and natto, being more infectious to Bacillus strains isolated from the chungkookjang, but much less active against a natto strain. Bp-K2 is a small DNA phage whose genome size is about 21 kb. Bp-K2 is a tailed bacteriophage with an isometric icosahedral head (50 nm long on the lateral side, 80 nm wide), a long contractile sheath (85-90 nm 9 28 nm), a thin tail fiber (80-85 nm long, 10 nm wide), and a basal plate (29 nm long, 47 nm wide) with a number of spikes, but no collar. The details of the structures of Bp-K2 differ from natto phage /BN100 as well as other known Bacillus phages such as SPO1-like or / 29-like viruses. These data suggest that Bp-K2 would be a new member of the Myoviridae family of Bacillus bacteriophages.
Regulation of the number of α‐bungarotoxin binding sites in cultured chick myotubes by a 1,4 dihydropyridine calcium channel antagonist (1988)

Calcium has been suggested as the second messenger link between skeletal muscle activity and AChR gene expression and synthesis. We have compared the concentrations of the Ca2+ channel antagonists D600 and nisoldipine needed both to block Ca2+ uptake into cultured myotubes and to increase AChR expression. The good correspondence between these two measurements and the use of the highly specific Ca2+ channel antagonist nisoldipine strengthens the hypothesis that AChR expression is regulated by levels of intracellular Ca2+.
Intrinsic Cardiac Ganglionic Neurons Projecting to the SA node in the Rat and Pig Hearts: Retrograde Labeling and Neurolucida 3‐D Reconstruction (2019)

Intrinsic cardiac ganglionic neurons (ICNs) within the heart are essential for regulation of cardiac function. ICNs include afferent, efferent neurons and interneurons and constitute a local integration center. In rat and pig hearts, there are multiple cardiac ganglia. Among these ganglia, the largest ganglionated plexus in the rat heart and the right atrial ganglionic plexus (RAGP) in the pig heart are near the sinoatrial node (SAN). However, it is not clear whether both plexi project to the SAN. In this study, retrograde tracer Fast DiI was injected into the SAN in rats (n=5) and a pig. SAN cells were identified by immunostaining for pacemaker channel HCN4. Fluorogold (FG) was injected (i.p.) to label all of the ICNs in rats. FG‐ and DiI‐labeled ICNs were identified and analyzed using a confocal microscopic system and a Neurolucida Tracing and Digitization System. Sixteen days after Fast DiI injection in rats, the animals were perfused with paraformaldehyde, and the whole‐mount atria were prepared. There were multiple ganglionated plexi and the DiI‐labeled neurons were mainly found in the largest ganglionated plexus near the SAN in all these rats. Twenty‐one days after Fast DiI injection in the pig, the animal was sacrificed, and the RAGP was removed and sectioned at 40 μm. Numerous DiI‐labeled neurons were found in the RAGP of this pig. Interestingly, these DiI‐labeled neurons were organized in five spatially‐separated columns perpendicular to the epicardial surface. Our data suggest that the largest ganglionated plexus in rat indeed projects mainly to the SAN, and the pig RAGP projects very heavily to the SAN. The functional significance of this large ganglionated plexus in rat and the five spatially‐separated columns of RAGP ICN projecting neurons in the pig will be elucidated in the future.

Analysis of Trim Commands on Overprovisioning and Write Amplification in Solid State Drives (2012)

This paper presents a performance model of the ATA/ATAPI SSD Trim command under various types of user workloads, including a uniform random workload, a workload with hot and cold data, and a workload with N temperatures of data. We first examine the Trim-modified uniform random workload to predict utilization, then use this result to compute the resultant level of effective overprovisioning. This allows modification of models previously suggested to predict write amplification of a non-Trim uniform random workload under greedy garbage collection. Finally, we expand the theory to cover a workload consisting of hot and cold data (and also N temperatures of data), providing formulas to predict write amplification in these scenarios.
