Multibeam healing for laser micromachining of scintillator arrays (2011)

Cost-effective, high-performance detectors are in high demand for use in positron emission tomography (PET) and other clinical and pre-clinical nuclear medicine imaging systems. Such detectors require high-resolution, high-sensitivity pixelated scintillator arrays. Scintillators with high stopping power, such as lutetium oxyorthosilicate (LSO) and lutetium-yttrium oxyorthosilicate (LYSO), are widely used in PET. However, the mechanical pixelation of such materials (especially to achieve <;1×1 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> pixels), yield issues, and their assembly into arrays is expensive and results in small fill factors (large inter-pixel gaps) and, hence, lower detector sensitivity than desired. Laser pixelation of scintillator material can potentially increase scintillator fill factor, resulting in higher sensitivity and yield and lower costs. We have adopted a multibeam laser micromachining approach to pixelate LSO with enhanced yield and improved throughput. The results of the experiments and the finite-element modeling are discussed here.
EUVI: the STEREO-SECCHI extreme ultraviolet imager (2004)

The Extreme Ultraviolet Imager (EUVI) is part of the SECCHI instrument suite currently being developed for the NASA STEREO mission. Identical EUVI telescopes on the two STEREO spacecraft will study the structure and evolution of the solar corona in three dimensions, and specifically focus on the initiation and early evolution of coronal mass ejections (CMEs). The EUVI telescope is being developed at the Lockheed Martin Solar and Astrophysics Lab. The SECCHI investigation is led by the Naval Research Lab. The EUVI’s 2048 x 2048 pixel detectors have a field of view out to 1.7 solar radii, and observe in four spectral channels that span the 0.1 to 20 MK temperature range. In addition to its view from two vantage points, the EUVI will provide a substantial improvement in image resolution and image cadence over its predecessor SOHO-EIT, while complying with the more restricted mass, power, and volume allocations on the STEREO mission.
Proposal of a simplified monitoring approach of environmental performances of farm tractors through a local telemetry network (2013)

The TRAKTnet.one project of the Free University of Bolzano aims to identify and develop new solutions to remotely monitor the efficiency of farm-tractors engines included in a local voluntary network all along their lifespan. The knowledge of tractors’ efficiency can give important information concerning machines’ consumption, emissions and need for servicing, thus contributing to a more environmentally-sustainable agriculture. Engines will be monitored by measuring rpms, exhaust gases’ temperature and oxygen content (as indexes indirectly estimating consumption and efficiency) and then analysing and inferring the data through procedures, which algorithms will be an integral part of the project’s results. This implies the existence of a service centre controlling all farm machines and managing a Farm-Information-Systems network through simple logical connections according to a client-server approach. The final outcome of the project is expected to be an automatic system, based on an inference software-engine able to correctly interpreting the sensors outputs. The advantage of this proposal is to exploit a farm monitoring network, previously designed for managing the information related to the automatic compilation of records in the country, by simply equipping data loggers with two additional sensors.
Subversion of host immune responses by Macobacterium tuberculosis (2010)

Tuberculosis, one of the world's oldest diseases has nowadays reached a pandemic prevalence. Despite its long history and intense research, efficient drugs against its causative agent, M. tuberculosis, are still limited. One reason for the pathogen's success lies within its capability to evade host immune defense mechanisms and to create a niche within host cells enabling the bacterium to persist for long periods. M. tuberculosis has evolved a diversified set of strategies to manipulate the immune response of the host. In this communication, we discuss some of the strategies employed by M. tuberculosis in order to survive within the hostile environment of the macrophage. A detailed analysis of the molecular basis of host-pathogen interactions will unravel novel mechanisms and might contribute to finding novel approaches to treat and combat tuberculosis.

[Diagnosis of alcohol-induced liver cirrhosis by indirect portal vein pressure measurement and liver venography]. (1992)

Indirect measurement of portal pressure and hepatic venography using the balloon catheter technique were investigated to assess the stage of chronic alcoholic liver disease, especially, to diagnose cirrhoses. 80 patients were studied and were categorised in 4 groups according to their liver histology: normal liver (N, n = 6), fibrosis (F, n = 27), incomplete cirrhosis (F/C, n = 11), complete cirrhosis (C, n = 36). Medians of wedged hepatic venous pressure gradient P (= WHVP-FHVP) and of a semiquantitative venographic score S showed increasingly higher values with more severe stages of the disease. Portal pressure (P) and venographic appearance (S) were correlated significantly (r = 0.778, p less than 0.0001). P was most useful to diagnose cirrhosis: Precirrhotic forms were associated with pressure gradients P less than or equal to 5 mm Hg in 97%. Incomplete cirrhoses were distributed in about 50% above and below P = 5 mm Hg, for complete cirrhoses P greater than or equal to 8 mm Hg was found in 97%. Pressure gradients P greater than or equal to 5 mm Hg indicated cirrhotic disease with a specificity of 97%. Sensitivity for complete cirrhoses was also high (97%), for incomplete cirrhoses however low (47%). Venography and measurement of portal pressure as diagnostic tools to predict cirrhoses of alcoholic origin were clearly more useful than biochemical tests (serum bilirubin, quick and cholinesterase). In comparison to laparoscopy the acceptance by patients is higher and the risk is lower if patients with known adverse reactions to contrast materials and risk of thyreotoxicosis induced by iodine are excluded.
MICRO-MACHINED THIN FILM HYDROGEN GAS SENSORS (2002)

The ability to detect gaseous hydrogen is of critical importance to acceptance and utilization of hydrogen as an energy carrier. Micro-machined gas sensors are a new generation of sensor technology combining existing integrated circuit fabrication technology with novel deposition and etching processing. This results in a new device structure, known as a “micro-hotplate”, which consists of an integrated hotplate on a suspended thermal isolation structure. This structure allows the sensor to operate at elevated temperatures, and provides a platform where the operating temperature can be rapidly changed to achieve desired response characteristics. ATMI has been developing novel thin film materials to function as hydrogen-selective active layers on top of micro-hotplate devices. This combination of micro-hotplate and novel active thin film materials has led to hydrogen sensors that demonstrate an array of highly desirable features, such as fast response speeds, low-level sensitivity, and amenability to mass production. These sensors are adaptable to a wide variety of sensing applications for a hydrogen-based energy economy, spanning from hydrogen based process monitoring to life safety protection. This paper describes recent efforts and progress made in developing micro-hotplate based hydrogen gas sensors at ATMI. This progress includes designing the sensor geometry to reduce power consumption and investigating the cross sensitivity to several contaminant gases – carbon monoxide, hydrogen sulfide, and isopropyl alcohol. Portable signal conditioning hardware was developed to help study long-term operation stability. Future work will be directed towards continuous improvement of the fabrication process and the development of new application specific operational models.
Theoretical design of high-performance polymer-based magnetoelectric of fibrilar structures (2017)

Low-dimensional magnetoelectric (ME) materials are attracting high attention both from the scientific and technological communities due to their interesting electrical, optical and mechanical properties allied to their novel applications in micro and nano smart-devices, drug delivery platforms, heterogeneous catalysis, tissue engineering, biosensors and bio-actuators, among others. Once the low dimensionality of these materials complicate the direct measurement of their performance at a large range of magnetic fields and high filler contents, this work theoretically evaluates low dimensional ME structures from spherical to ellipsoidal and fibre-shaped. The structures are based on CoFe2O4/poly(vinylidene fluoride) composites and the simulations are performed through the finite element method (FEM). Results for 50 wt percentage (wt.%) CoFe2O4 content samples reveal ME coefficients of 182 V/cm at 684 Oe for the spheres and 4241 V/cm at a magnetic field of 208 Oe on the medium eccentricity (of 1200) ellipsoidal structure. These fibre shaped ellipsoids exhibit higher ME values than the spheres and the axisymmetric fibres: 1601 V/cm at 30 Oe for an ellipsoid with eccentricity of 3200. Further, the fibrilar structure strongly decreases the ME performance and operational magnetic field to 14.7 V/cm at 1.38 Oe. These results establish the potential and limits, in terms of magnetic field and electric response, of the use of these composites and structures on technological ME device applications. Further, it demonstrates that suitable tuning of shape and dimensions allow to strongly increase ME response of the composites.

RADIO AND MOBILE PHONE OWNERSHIP OR ACCESS BY SMALLHOLDER FARMERS OF EASTERN UGANDA AND ITS POTENTIAL USE FOR PUSH-PULL TECHNOLOGY DISSEMINATION (2017)

A baseline survey of ownership or access to radio and mobile phone was conducted in seven districts of eastern Uganda in 2015. The purpose of this survey was to assess the role of radio and modern communication technologies to promote push-pull technology as an integrated management approach to control striga and stemborer and improve soil fertility.  The selected districts are where icipe is currently disseminating the technology.  The survey was conducted from seven districts where 30 respondents from each were identified for the study. Semi structured questionnaires were administered where data including household demography, ownership and or access to radio and mobile phone was collected. The data were analyzed using STATA (version 13).  The findings show that there are over eight (Ateso, Luganda, Samia, Japadhola, Lugisu, Lusoga, Kiswahili, and English) languages spoken in the surveyed districts. Most of the respondents speak more than one language. Overall, ownership of radio and mobile phone was at 82% and 87% respectively with slight differences between men and women. Moreover, those who do not own radio and mobile phones also stated that they have access to one. On average, 83% of the respondents (174 out of 210) said that they do receive text messages, whereas, only 53% of the respondents indicated that they also send text messages. A great proportion of the respondents (91%, 80%, and 77%) received agricultural, weather and market information through the radio. Over 65% of the respondents reported benefiting from the agricultural programs broadcasted via radio. 45 and 50% stated that they benefitted from market and weather information. However, the level of benefit rendered from mobile phones with regard to agricultural, market and weather information was negligible. The study showed that radio and mobile phones are best suited mass communication media to transfer technologies such as push-pull to address cross-cutting problems such as striga, cereal stem borer and low soil fertility. It will strengthen the agricultural extension service delivery at large.
Preparation of New Nitrogen-bridged Heterocydes. 8. Syntheses of Some Fused Indolizine Derivatives via the Acid-catalyzed Cyclizations of Functionalized 1- and 3-Vinylindolizines (1984)

Abstract Pyrano[3,2-a] and pyrano[2,3-b]indolizin-2-one derivatives were prepared in 12–86% yields by the acid-catalyzed deacetylation-cyclization of 2-acetoxy-1- and 3-[2-(ethoxycarbonyl)vinyl]indolizines with concentrated sulfuric acid at room temperature. On the other hand, similar reactions of 2-acetoxy-3-[1,2-bis(methoxycarbonyl)vinyl]indolizines did not give the initially expected pyrano[2,3-b]indolizinones at all, but, instead of them, afforded 3-(methoxycarbonylmethylene)furo[2,3-b]indolizin-2-one derivatives in fair yields. Formation mechanisms and some physical properties are also discussed.

Language of Education Planning in Zambia (2014)

Zambia is a landlocked country in south central Africa. While its only official language is English, seven other languages are recognized as national languages. In addition, many other local languages are used. In education, however, not all Zambian languages are taught as subjects or used as mediums of instruction. This paper reviews the history of languages and their use in the educational system in Zambia. After considering what was done in the past, the current policies are examined. Finally, a Game Theory analysis is used to predict what kind of language of education policy would be most agreed upon in contemporary Zambia. “One Zambia, One Nation ” was the motto adopted when Zambia gained independence from the British in 1964. This motto highlighted the people’s desire to become a unified nation after being disintegrated during the colonial period (Marten &amp;amp; Kula, 2007). Following the belief that “one nation equals one language, ” Zambians
Threshold-Based Relaying in Coded Cooperative Networks (2010)

In cooperative communications, error propagation at the relay nodes degrades the diversity order of the system. To combat that effect, we present a novel technique to control error propagation at the relays, which is implemented in the context of a distributed turbo code. In the presented technique, the relay calculates the log-likelihood ratio (LLR) values for the bits sent from the source. These values are subjected to a threshold to distinguish the reliable bits from the unreliable bits. The relay then forwards the bits that are deemed reliable and discards the bits that are not, resulting in fewer errors propagating to the destination. The assumption here is that the destination does not know the location of the discarded bits. We develop upper bounds on the end-to-end bit error rate, enabling us to optimize the threshold in terms of the minimum end-to-end bit error rate. We compare our technique with existing techniques that have been proposed to control error propagation, including using only a cyclic redundancy code check at the relay, forwarding analog LLR values, and by employing no error control at the relay at all. We demonstrate, through several numerical examples, that the proposed scheme outperforms all existing schemes.
Management of RF Energy Harvesting: A Survey (2019)

Advancement in energy harvesting technologies has inspired new ways of supporting industrial applications especially in harsh environment with almost everlasting free power. There are several sources such as solar, wind, vibration, radio frequency (RF), etc. and each source has its own characteristics. RF poses unique characteristics which make it a good candidate for specific applications such as indoor sensor networks. However, due to the scarcity of harvested power, it is essential to manage this power efficiently taking into consideration the quality of service requirements. In this paper, we classified the power management techniques into two major classes: soft and hard techniques; soft techniques such as MAC protocols, while hard techniques RF harvester circuit design. In this work, we survey the literature for the existing soft power management techniques for Radio Frequency (RF) energy harvesting based sensor networks. Then, we shed light on the major challenges and open issues in building a sustainable RF energy harvesting based wireless sensor networks.

Effect of crystal structure on magnetic-field-induced strain in Ni-Mn-Ga (2003)

Magnetic shape memory materials are expected to have a high potential in practical applications. Several ferromagnetic materials exhibiting the large magnetic-field-induced strain have been found in recent years. The largest field-induced strain is observed in Ni-Mn-Ga system. The most important experimental results on crystal structure, magnetic anisotropy and twinning stress of martensitic phases in Ni-Mn-Ga having tetragonal five-layered, orthorhombic seven-layered and tetragonal non-layered crystal structures are reported. Depending on the martensite crystal structure Ni-Mn-Ga alloys are able to show a really giant strain response (approximately 6% in tetragonal five-layered or 10% in orthorhombic seven-layered martensitic phase) in a magnetic field less than 1 T. Contrary to these two phases, a detectable field-induced strain is not observed in non-layered tetragonal martensitic phase in Ni-Mn-Ga system. Effect of crystal structure is in a good agreement with calculation of the magnetic-field-induced strain based on the model developed by authors. The effect of composition on appearance of undesirable non-layered tetragonal martensitic phase in Ni-Mn-Ga system is discussed based on the new experimental results.

Development of amber suppressor tRNAs appropriate for incorporation of nonnatural amino acids (2006)

An amber suppression method has been used for incorporation of nonnatural amino acids into proteins. However, the incorporation efficiency of nonnatural amino acids through an amber codon has been low, which restricts the application of the proteins containing nonnatural amino acids. In this study, we screened a wide variety of amber suppressor tRNAs to discover tRNAs capable to incorporate nonnatural amino acids with high efficiency. To this purpose, synthetic amber suppressor tRNAs of E. coli and Mycoplasma capricolum were screened for the incorporation of a fluorescently labeled nonnatural amino acid in an E. coli cell-free translation system. tRNAs that showed high capability for the incorporation were then mutated not to be aminoacylated by any of endogenous aminoacyl-tRNA synthetases of E. coli and to enhance the incorporation capability. As a result of these investigations, we successfully obtained several amber suppressor tRNAs with high ability for the incorporation of nonnatural amino acids.
