Cover Picture: Doubly Renewable Cellulose Polymer for Water‐Based Coatings (ChemSusChem 1/2015) (2014)

The Front Cover image shows the passage of plant material into paint. First comes cellulose, which is esterified with the bio-derived levulinic acid, forming a novel cellulosic ester. Additional chemical manipulations modify the physical properties of the polymer, such that self-dispersion and formation of a stable aqueous colloid is achieved. The precipitated particles are spontaneously film-forming at ambient temperature, which allows the product to be formulated into paint. More details can be found in the Communication by Hinkley and co-workers on page 63 (DOI: 10.1002/cssc.201402590), while more information about the research group is available in the Cover Profile (DOI: 10.1002/cssc.201402906).
Artificial Water Channels (2020)

Natural systems have evolved for millions of years to transport metabolites across cell membranes. Among them, Aquaporins (AQPs) are biological channels known for fast water transport with ion exclusion. AQPs can be mimicked using simpler artificial water channels (AWCs) to explore the naturally evolved water transport in artificial systems and to assess the basis for biomimetic desalination processes. Selective water translocation has been shown to depend on water wires spanning the pore that induce dipolar orientation. Toward this objective, AWCs combining a particularly broad range of self-assembling features including H-bonding, water recognition, and hydrophobic effects. This might play an important role in the ability to finely control the hydrophilic or hydrophobic constitutional domains of the channel responsible for selective recognition and high-water translocation, respectively. Then, densely packed AWCs incorporated within TFC polyamide membranes will lead to a greater fundamental understanding of how selective pores can be optimized at the nanoscale to facilitate ultrafast and highly selective transport of water for the treatment of saline feed streams. Future routes to robust desalination membranes including AWCs will solve pressing challenges, such as the stability, scalability, and fabrication of membrane for water desalination, ultrapure water production, as well as the storage of clean energy applications.
Isolation, karyotype, and clonal growth of heterogeneous subpopulations of human malignant gliomas. (1981)

Abstract The histological pleomorphism of human malignant gliomas as well as their variable response to therapy suggests that such tumors are not homogeneous but are composed of a heterogeneous population of cells. To search for heterogeneity in these tumors, we developed a protocol to identify by karyotype, isolate, and clone the subpopulations of the tumor. Freshly resected tumors were mechanically dissociated into single cells that were grown in suspension and short-term monolayer cultures. Chromosomal preparations were collected over the first 6 to 72 hr postresection. The karyotypes prepared comprised the “reference set” of chromosomes found in each tumor. The dissociated single cells were also dilution plated for monolayer culture. Cells that attached were marked and isolated as clones whose karyotypes were compared to those in the reference set in order to identify those clones that were cellular representatives of the tumor. Explant cultures established from the same tumor were grown in monolayer culture and cloned; their karyotypes were likewise compared to those in the reference set. Eight gliomas were analyzed. Each had metaphases that ranged in chromosome number from hypodiploid to hyperploid, but the frequency distribution of the subpopulations differed among the tumors. Defining a cellular subpopulation in the tumor as one yielding at least five karyotypically identical cells in the reference set, we found that each tumor contained from three to 21 subpopulations. All but one tumor produced 100 or more clones, and in seven tumors, more than 50% of the clones could be expanded for karyotyping; 7.6 to 25% of these clones had karyotypes identifiable in the reference set of their tumor. There was little relationship between the morphology of the clones and their karyotypes or growth kinetics. While explant cultures grew well, no clone derived from such cultures could be identified in the reference set. The protocol permits studies of clonal lines identifiable as cellular representatives of a patient9s tumor and not variants generated in tissue culture. These studies confirmed that human malignant gliomas are comprised of karyotypically heterogeneous cellular subpopulations. Preliminary work suggests that their phenotypic behavior may be similarly heterogeneous.
The role of proctosigmoidoscopy in laparoscopic pelvic surgery (2000)

Objective: To evaluate the efficiency and safety of rigid sigmoidoscopy during operative laparoscopy in patients at high risk for rectosigmoid and large bowel disease or injury. Methods: We conducted a prospective study of 262 women treated for rectosigmoid endometriosis and adhesions at the Center for Special Pelvic Surgery in Atlanta, Georgia. All of the subjects underwent a rigid sigmoidoscopy during laparoscopy. At the end of surgery, proctosigmoidoscopy was performed for the evaluation of any intraluminal abnormality or rectosigmoid injury. The pelvis was then filled with isotonic fluid to observe laparoscopically any air leakage. Results: Sigmoidoscopy was indicated due to a lesion involving the rectum or sigmoid in 60.7%, the large bowel in 11.1%, and the posterior cul-de-sac in 28.2% of the cases. The primary indication for surgery was pelvic pain, endometriosis, or adhesions in 88.6%. During laparoscopy, endometriosis was found in 30.5%, adhesions in 20.2%, and both in 43.5%. Intentional or unintentional bowel perforation occurred in 44 (16.8%) patients. In four (1.5%) patients, the bowel injury was identified during sigmoidoscopy. All participants were treated by intracorporeal laparoscopic suturing. One incomplete repair was detected by sigmoidoscopy. In 1 (0.4%) case, a rectal polyp was detected. Conclusions: Bowel injury is recognized as one of the most serious complications of laparoscopy. Early recognition and prompt intraoperative management are essential to prevent a potentially catastrophic outcome. Sigmoidoscopy is a relatively easy procedure during laparoscopy and aids in the diagnosis of bowel perforation and in assessment of bowel wall invasion and any potential stricture caused by endometriosis. It is a safe procedure, even when performed immediately after extensive laparoscopic surgical treatment of rectosigmoid endometriosis and adhesions. Sigmoidoscopy may be used with discretion as a diagnostic and risk management tool during laparoscopic surgery of the rectosigmoid colon.
Is freezing of gait in Parkinson's disease related to asymmetric motor function? (2005)

Freezing of gait (FOG) is a disabling phenomenon common in patients with advanced Parkinson's disease (PD). The cause of FOG is unclear. The objective of this study was to explore a novel hypothesis stating that FOG is related to asymmetric motor performance. We compared PD patients that experience FOG episodes (PD+FOG) with PD patients that do not (PD-FOG) and studied the relationship of FOG to asymmetry in gait and in rhythmic hand movement performance to determine whether potential FOG-related gait asymmetry is unique to walking or whether it is systemic. Subjects were tested in an "off" (unmedicated) and again in an "on" (medicated) state. Gait was more asymmetric in PD+FOG than in PD-FOG during "off" state (p = 0.005) and during "on" (p = 0.016). Rhythmicity of foot swing in one leg was correlated with the other leg in PD-FOG but not in PD+FOG. There was no difference in asymmetry in performance of rhythmic hand movements between the two groups. No correlation was found between asymmetry of clinical symptoms and gait asymmetry. Taken together, the results of this study suggest that bilateral uncoordinated gait and marked gait asymmetry, but not asymmetry in motor performance in general, are associated with FOG.

DUNBLAD, the Delft University neutron backscatter landmine detector (2003)

The neutron backscattering technique may be applied to search for non-metallic land mines in relatively dry soils. A novel, ergonomic detector system has been constructed. Tests with real land mines in a realistic environment show that anti-tank mines can reliably be found, but that anti-personnel mines may escape detection. The performance could be improved when an image of the mine signal could be obtained. One approach is to use an array of position sensitive <sup>3</sup>He detectors placed close to the soil. A first test with a pulsed neutron generator shows that further improvements can be made by applying a time window on the neutron transit time. The possibilities of neutron backscattering imaging systems are investigated using Monte Carlo simulations with GEANT. A neutron backscattering imaging device with a 2D sensitive detection plane is currently under development.
Stereo video completion for rig and artefact removal (2012)

Video reconstruction has become an important tool for rig and artefact removal in cinema postproduction. In this paper we are concerned with reconstructing stereo video material. We propose a method that builds on existing exemplar-based video inpainting techniques and includes a dedicated view consistency constraint. Within a constrained texture synthesis framework, we use reconstructed motion and inter-frame disparity vectors as guides for finding appropriate example source patches from parts of the sequence that minimise spatial and stereo discrepancies. We then introduce coherent patch sewing to reconstruct the missing region by stitching the source patches together. Compared to previous methods our results show increased spatial and view consistency.
GoDec: Randomized Low-rank & Sparse Matrix Decomposition in Noisy Case (2011)

Low-rank and sparse structures have been profoundly studied in matrix completion and compressed sensing. In this paper, we develop Go Decomposition (GoDec) to efficiently and robustly estimate the low-rank part L and the sparse part S of a matrix X = L + S + G with noise G. GoDec alternatively assigns the low-rank approximation of X - S to L and the sparse approximation of X - L to S. The algorithm can be significantly accelerated by bilateral random projections (BRP). We also propose GoDec for matrix completion as an important variant. We prove that the objective value ||X - L - S||2F converges to a local minimum, while L and S linearly converge to local optimums. Theoretically, we analyze the influence of L, S and G to the asymptotic/convergence speeds in order to discover the robustness of GoDec. Empirical studies suggest the efficiency, robustness and effectiveness of GoDec comparing with representative matrix decomposition and completion tools, e.g., Robust PCA and OptSpace.

Efficacy of aucubin as a nitrification inhibitor assessed in two Canterbury field trials (2019)

ABSTRACT Ruminant urine patches are nitrous oxide (N 2 O) emission hot‐spots and compounds that inhibit nitrification in urine‐affected soils, a key step in soil N 2 O production, can significantly reduce N 2 O emissions. Aucubin, a potential nitrification inhibitor found in plantain ( Plantago lanceolata ) was assessed in two field trials for its efficacy in reducing urine patch nitrate (NO 3 − ) accumulation and N 2 O emissions. Plantain leaf extract or commercially derived pure aucubin was added to urine, alongside a control and urine only treatment, and applied to standard gas chambers and monitored for 35 days. While there were some daily differences between treatment soil nitrogen and N 2 O emissions, there were no overall significant differences between cumulative N 2 O emissions. Aucubin, applied as a one‐off dose, seems to act as a nitrification inhibitor for a short period after application onto soil, but it’s inhibitory effects are not sufficient to produce significant reductions in overall urine patch N 2 O emissions.
Cooperative Recovery in Heterogeneous Mobile Networks (2008)

In multicast/broadcast services over infrastructure- based/cellular wireless networks (e.g. 3G cellular networks, WiMax, DVB), data is transmitted to multiple recipients from an access point/base station. Multicast greatly improves the network efficiency to distribute data to multiple recipients as compared to multiple unicast sessions of the same data to each receiver individually, by taking advantage of the shared nature of the wireless medium. However it is difficult to guarantee the reception reliability of multiple multicast/broadcast recipients because the wireless medium is error prone and each receiver experiences different channel conditions. An additional difficulty is that multicast/broadcast services in many networks such as 3G multimedia multicast services do not provide a reverse communications channel for the receivers to request the retransmission of lost data packets. This research proposes a novel method to provide QoS support by using an assistant network to recover the loss of multicast data in the principal network. Wireless devices are connected to the principal network to receive the multicast data. A wireless device may lose some of the multicast data sent over the principal network. The wireless devices form an assistant network to recover the lost multicast data cooperatively from their peers. The performance of this recovery mechanism has been investigated using extensive simulation experiments.
Impact of aquaculture field school on community fish farming (2016)

Community based aquaculture, a subset of the rural aquaculture, is characterised with low fish production level. Sustainable improvement of productivity levels in such resources has remained a challenge. The study adopted a novel approach of technology transfer through aquaculture field school which involves provision of technical advices and no physical inputs. The article tries to capture its impact on fish production levels and economics of community based aquaculture. The study was conducted during 2009-2012 in Khurda and Puri districts of Odisha by surveying randomly selected farmers of community ponds. Demonstration, need-based skill training, field days, workshops and field visits were organised periodically for fish farmers involved in community based aquaculture management. In order to study the impact of technical inputs, data were collected from 31 randomly selected village community ponds. Farmers provided with technical advices could improve pond management practices significantly (p&lt;0.05). This included eradication of aquatic weeds, removal of weeds and predatory fishes, enhancing pond productivity, stocking fingerlings and/or yearlings, partially feeding fish with locally available feed. This has resulted in better fish production (@ 2192 kg ha-1yr-1) than pre-project period (@1081 kg ha-1yr-1). Motivational drive, need based technical advice and follow up action brought behavioral change in fish farmers for higher investment for intensification of pond management. Average expenditure in community based aquaculture rose significantly (p&lt;0.05) from `40146 ha-1yr-1 to `87071 ha-1yr-1. Average net returns from community ponds at the end of the project period increased to `95068 ha-1 yr-1 against `34057 ha-1yr-1.
Miniaturized micro-optical scanners (1994)

Optical beam scanners are critical components for airborne and space-based laser radar, on-machine-inspection systems, factory automation systems, and optical communication systems. We describe here a laser beam steering system based on dithering two complementary (positive and negative) microlens arrays. When the two microlens arrays are translated relative to one another in the plane parallel to their surfaces, the transmitted light beam is scanned in two directions. We have demonstrated scanning speeds up to 300 Hz with a pair of 6-mm-aperture microlens arrays designed for input from a HeNe laser. The output beam covers a discrete 16 x 16 spot scan pattern with about 3.6 mrad separation and only 400 μrad of beam divergence, in close agreement with design predictions. This demo system is relatively compact; less than 2 in. on a side. We also describe several near-term applications, some critical design trade-offs, and important fabrication and design issues.

<title>Electrorheological damper analysis using an Eyring-plastic model</title> (2002)

This paper presents experimental and theoretical analysis of an electrorheological (ER) damper. To describe the practical damper characteristics on force vs. velocity and force vs. displacement responses, a new alternative to existing models is proposed. On the basis of an Eyring model, Eyring-plastic model is constructed by the combination of simple nonlinear functions. Therefore, the Eyring-plastic model has the advantage to be simple in its design and formulation, even though it is in the form of a nonlinear function. In addition, the Eyring-plastic model can capture quite well the practical damper responses, particularly, in both the preyield and the postyield states. An ER damper is configured and its damping force under various electric fields and excitation frequencies is experimentally tested. On the basis of the damper response tested, the Eyring-plastic model is constructed and its validation is proved by comparing the experimental and predicted damper data on force vs. velocity and force vs. displacement responses.
