Computer Vision Aiding Smartphone Sensors for Indoor Location Applications (2015)

Modern mobile phones are powerful processing devices with a host of onboard technologies of interest to navigation system designers. In the absence of Global Navigation Satellite System (GNSS) information, the accelerometers and gyroscopes within a smartphone can be used to provide a relative navigation solution. However, these micro-electro-mechanical systems (MEMS) based sensors suffer from the effects of various errors which cause the inertial-only solution to deteriorate rapidly. As such, there is a need to constrain the inertial positioning solution when long-term navigation is needed. GNSS positions and velocities, and WiFi positions when available, are the most important forms of updates available for the inertial solution. However, updates from these two sources depend on external signals and infrastructure that may not always be available. One attractive source of updates is through the use of a vision sensor. This work describes the development of a vision-based module that determines the device heading misalignment and context based on a sequence of images captured from the device camera. The vision aiding module checks for static periods and calculates the device heading misalignment when in motion. Context classification is assessed for five common use cases: (1) fidgeting the phone while standing still (“fidgeting” context), (2) phone on ear on one floor (“single floor calling” context), (3) phone on ear on stairs (“stairs calling” context), (4) phone in hand on a single floor (“single floor texting” context), and (5) phone in hand on stairs (“stairs texting” context). The module was tested using real-time video and inertial data collected using a Samsung Galaxy S3 smartphone running the Android 4.0 operating system. The results show successful detection of the aforementioned use cases and accurate device angles. Integration of the vision aiding module with a pedestrian dead reckoning (PDR) system shows improvements to the position solution.
Oestrogen action on the myocardium in vivo: specific and permissive for angiotensin-converting enzyme inhibition (2002)

Oestrogen replacement is permissive for the beneficial effects of ACE-inhibition in female SHR rats. Oestrogen effects on the myocardium in vivo are specific (i.e. oestrogen receptor mediated) because they are inhibited by a pure oestrogen receptor antagonist and occur at physiological hormone levels.
Spectroscopic studies of trans-bis(hexafluroarsenato)tetrakis(thiazyl trifluoride)metal(II) complexes (M = Mn, Fe, Co, Ni, or Cu); crystal structure of the manganese(II) complex: an example of exceptionally short N–S bonds and of AsF6–as a unidentate ligand (1981)

The i.r. spectra of the series [M(NSF3)4(AsF6)2](M = Mn, Fe, Co, Ni, or Cu) indicate that the compounds are isostructural, with trans-AsF6 groups co-ordinated to the metal atom, and N–S bonds appreciably stronger than in free NSF3. This is confirmed by the crystal structure of trans-[Mn(NSF3)4(AsF6)2]. It crystallises in the monoclinic space group P21/n, with a= 7.496(4), b= 10.378(5), c= 13.979(6)Å, β= 94.33(3)°, and Z= 2. The structure was refined to R= 0.048 for 1 226 diffractometer data. The metal ion is octahedrally co-ordinated, with Mn–Nav. 2.187, Mn–F 2.193(4), and N–Sav. 1.365 Å.
Manipulation method for the treatment of ankle equinus (2000)

Ankle equinus is a well-known clinical entity that has previously been shown to compound a variety of foot and ankle conditions. Treatments for this disorder have included surgery to lengthen the Achilles tendon and daily stretching. This article describes a method of manual manipulation that can immediately and substantially increase ankle joint dorsiflexion. Patients treated with manipulation in the current study demonstrated nearly twice as much dorsiflexion motion as that demonstrated by patients in a prior study who were treated with a 5-minute daily stretching program for 6 months.

Part I: Method of Nourishment of the Barnes Ice Cap (1952)

Abstract The Barnes Ice Cap on Baffin Island, N.W.T., Canada, was investigated during the summer of 1950. This ice cap, some 6000 sq. km. in extent, appears to have an approximately balanced budget, and yet there is no firn on its surface. It is postulated that its nourishment is by superimposed ice due to immediate refreezing of much of the melt water of summer. It is further inferred that a similar process nourishes many Arctic glaciers and ice caps where elevation, precipitation and temperature are all low. The name “ Baffin Type ” is proposed for these in the classification of glaciers.
Electric field coupling to quantum dot diodes (1991)

We have fabricated two different structures in the GaAs/AlGaAs heterojunction system to quantify the transfer characteristics of the quantum dot subjected to external, local electric fields. The first structure is a single quantum dot diode with an annular field electrode placed adjacent to the double-barrier structure by a self-aligned fabrication process. A second structure consists of a pair of independently contacted quantum dot diodes separated by several hundred angstroms. The fabrication processes and transport properties for both of these structures are described. We have also attempted for the first time to form quantum dots in InGaAs/AlAs system lattice matched to InP and have observed that strong conductance fluctuations not related to lateral size quantization can occur. These fluctuations arise from the formation of rotation-induced finite superlattices.
SPATIAL VARIABILITY OF INDOOR RADON CONCENTRATION IN SCHOOLS: IMPLICATIONS ON RADON MEASUREMENT PROTOCOLS (2020)

The requirements about radon measurements in schools and public buildings included in most of the national and international legislations are generally restricted to all the rooms located at the ground floor and basement, assuming the soil beneath the building as the main source of indoor radon. In order to verify such an assumption for small buildings having at maximum two floors, a preliminary study was performed in 50 schools located in 15 municipalities of the Republic of Srpska. Results of this study suggest that a protocol requiring measurements at the ground floor only may be considered adequate. Due to the high radon spatial variability for rooms at the ground floor, it is preferable to require measurements in a high number of rooms (preferably in all of them) in order to assess the compliance with the reference level established by the legislation.
The Spanish Inquisition Protocol (2010)

The Spanish Inquisition Protocol (SIP) re duces Wireless Sensor Network (WSN) energy cost by transmitting only unexpected information and is so-named because "nobody expects the Spanish Inquisition!" SIP extends prior Dual Prediction Scheme (DPS) algorithms that model phenomena at both node and sink. SIP's key advancement is that it transmits a state vector estimate rather than individual readings. SIP can be tuned according to the desired estimate accuracy, with lower desired accuracy typically leading to fewer transmitted packets. In simulation with real data, less than 5% of the samples needed to be transmitted to provide the sink with an accurate estimate of the sensor value (within 0.5°C, in the case of temperature). SIP also significantly outperforms prior DPS results when using the same data sets. In deployment on Telos motes, SIP shows similar performance to the simulations.
Priming of T follicular helper cells by dendritic cells (2013)

T follicular helper cells (Tfh) are required to generate long-lived antibody responses, which confer long-term protection to pathogens following vaccination or infection. Despite significant advances in the field, however, little is known about the early steps that drive Tfh cell differentiation. In this review, we will discuss the mechanisms by which dendritic cells promote the initial commitment of activated CD4(+) T cells to the Tfh cell differentiation pathway.
Deciphering MET‐dependent modulation of global cellular responses to DNA damage by quantitative phosphoproteomics (2020)

Increasing evidence suggests that interference with growth factor receptor tyrosine kinase (RTK) signaling can affect DNA damage response (DDR) networks, with a consequent impact on cellular responses to DNA-damaging agents widely used in cancer treatment. In that respect, the MET RTK is deregulated in abundance and/or activity in a variety of human tumors. Using two proteomic techniques, we explored how disrupting MET signaling modulates global cellular phosphorylation response to ionizing radiation (IR). Following an immunoaffinity-based phosphoproteomic discovery survey, we selected candidate phosphorylation sites for extensive characterization by targeted proteomics focusing on phosphorylation sites in both signaling networks. Several substrates of the DDR were confirmed to be modulated by sequential MET inhibition and IR, or MET inhibition alone. Upon combined treatment, for two substrates, NUMA1 S395 and CHEK1 S345, the gain and loss of phosphorylation, respectively, were recapitulated using invivo tumor models by immunohistochemistry, with possible utility in future translational research. Overall, we have corroborated phosphorylation sites at the intersection between MET and the DDR signaling networks, and suggest that these represent a class of proteins at the interface between oncogene-driven proliferation and genomic stability.
Cationization of Eucalyptus grandis 4-O-methyl glucuronoxylan for application as a wet-end additive in a papermaking process (2013)

Abstract Hemicelluloses extracted prior to kraft pulping can subsequently be introduced as wet-end strength additives in a papermaking process. The 4- O -methyl glucuronoxylan (Me-GluX) extracted from Eucalyptus grandis (E. grandis) under mild alkaline conditions was cationized and added to bleached kraft pulp (BKP) from E. grandis before refining. The cationization by 2,3-epoxypropyltrimethylammonium chloride (ETA) was done in a central composite designed experiment. Me-GluX with an average molecular weight of 52,000 g mol -1 contained 27% Klason residue. The cationic Me-GluX had degrees of substitution of the cationic side chain between 0.05 and 0.73 and uronic acid content between 6.1% and 12.7%. The cationic Me-GluX as a wet-end strength additive was compared to cationic starch (CatStarch 134) in handsheets. The handsheets with cationic Me-GluX showed improvement in tensile, burst, and tear indices and had lower air permeability than those with CatStarch 134 at dosages between 1.0% and 2.0%. Accordingly, cationized Me-GluX is a potential green wet-end strength additive, which could fully or partially replace the synthetic and starch additives.
[131I]metaiodobenzylguanidine treatment of a malignant paraganglioma. (1992)

The bone metastases of a malignant, non-secreting paraganglioma were treated with [131I]metaiodobenzylguanidine (131I-MIBG) over a 10-year period. Initial treatment (131I-MIBG: 9.6 GBq) resulted in a decrease in the number of bone metastases from 16 to 2. At three years, a relapse with primary tumor regrowth and liver metastasis was again treated with 131I-MIBG (22.2 GBq). A decrease in the number of bone metastases and MIBG uptake was again observed.

A Robust and Flexible Control System to Reduce Environmental Effects of Thermal Power Plants (2011)

Regulations on environmental effects due to such issues as nitrogen oxide (NOx) and carbon monoxide (CO) emissions from thermal power plants have become stricter[1]; hence the need for compliance with these regulations has been increasing. To meet this need, several technologies with respect to fuel combustion, exhaust gas treatment and operational control have been developed[2-4]. The technologies for the fuel combustion and the exhaust gas treatment include a low NOx burner and an air quality control system, and they are capable of reducing impact on the environment as physical and chemical implementation methods. The operational control technology for the thermal power plants is constantly required to receive changes in operational conditions. It is difficult to realize operational control which responds to combustion properties. To overcome this issue, the operational control must be able to reduce NOx and CO emissions flexibly in accordance with such changes. Robustness is also required in such control because the measured NOx and CO data often include noise. Therefore, a robust and flexible plant control system is strongly desired to reduce environmental effects from thermal power plants efficiently. Several studies have proposed plant control technologies to reduce the environmental effects[4-10]. These technologies are classified into two types of methods: model based and non-model based methods. The former methods include an optimization algorithm and a numerical model to estimate plant properties using neural networks (NNs)[11,12] and multivariable model predictive control[13]. The optimization algorithm searches for optimal control signals to reduce NOx and CO emissions using the numerical model. The latter methods have no models and they generates the optimal control signals by fuzzy logic[14]. A fuzzy logic controller outputs the optimal control signals for multivariable inputs using fuzzy rule bases. The fuzzy rule bases are based on a priori knowledge of plant control, and they can be tuned by parameters. These technologies require the measured plant data for initial tuning of the model properties and the parameters of rules when the technologies are installed in plants. It usually takes some time to collect enough plant data. In addition, the search for control
Post-Lithium Batteries with Zinc for the Energy Transition (2023)

The energy transition is only feasible by using household or large photovoltaic powerplants. However, efficient use of photovoltaic power independently of other energy sources can only be accomplished employing batteries. The ever-growing demand for the stationary storage of volatile renewable energy poses new challenges in terms of cost, resource availability and safety. The development of Lithium-Ion Batteries (LIB) has been tremendously pushed by the mobile phone industry and the current need for high-voltage traction batteries. This path of global success is primarily based on its high energy density. Due to changing requirements, other aspects come to the fore that require a rebalancing of different technologies in the “Battery Ecosystem”. In this paper we discuss the evolution of zinc and manganese dioxide-based aqueous battery technologies and identify why recent findings in the field of the reaction mechanism and the electrolyte make rechargeable Zn-MnO2 batteries (ZMB), commonly known as so-called Zinc-Ion batteries (ZIB), competitive for stationary applications. Finally, a perspective on current challenges for practical application and concepts for future research is provided. This work is intended to classify the current state of research on ZMB and to highlight the further potential on its way to the market within the “Battery Ecosystem”, discussing key parameters such as safety, cost, cycle life, energy and power density, material abundancy, sustainability, modelling and cell/module development.
The Multiplication of Nodamura Virus in Insect and Mammalian Cell Cultures (1975)

Nodamura virus multiplied in mosquito cell lines, as determined by infectivivity assays in adult honey bees (Apis mellifera) and wax moth larvae (Galleria mellonella). Titres of more than 10-7 and 10-5 bee LD50 /ml were obtained in culture fluids of Aedes albopictus and Aedes aegypti cells respectively after 10 days. Comparable titres were obtained after several months, during which the cultures were subdivided up to six times. Nodamura virus also multiplied in BHK cells and yielded titres of 10-4-8 to 10-6-6 mouse LD50/ml and 10-5-1 to 10-7-1 wax moth LD50/ml in culture fluid 1 to 4 days after infection. No c.p.e. was observed in infected cells.

Synthetic-Ripple Modulator for Synchronous Buck Converter (2005)

Comprising a hysteretic comparator and a ripple synthesizer, the synthetic-ripple modulator (SRM) allows voltage-hysteretic modulation to be realized in low-voltage buck converters where the natural voltage ripple is too small for reliable hysteretic operation. Circuit implementation, steady-state operation, and design equations are described for an SRM controlling a buck dc-dc converter. The basics are verified experimentally by a buck converter switched at 420 kHz and delivering 10 A at 1.8 V.
Nucleic Acid and Non-Nucleic Acid-Based Reprogramming of Adult Limbal Progenitors to Pluripotency (2012)

Reprogramming somatic cells to a pluripotent state by nucleic acid based (NAB) approaches, involving the ectopic expression of transcription factors, has emerged as a standard method. We recently demonstrated that limbal progenitors that regenerate cornea are reprogrammable to pluripotency by a non-NAB approach through simple manipulation of microenvironment thus extending the possible therapeutic use of these readily accessible cells beyond the proven treatment of corneal diseases and injury. Therefore, to determine the validity and robustness of non-cell autonomous reprogramming of limbal progenitors for a wider clinical use, here, we have compared their reprogramming by non-NAB and NAB approaches. We observed that both approaches led to (1) the emergence of colonies displaying pluripotency markers, accompanied by a temporal reciprocal changes in limbal-specific and pluripotency gene expression, and (2) epigenetic alterations of Oct4 and Nanog, associated with the de-novo activation of their expression. While the efficiency of reprogramming and passaging of re-programmed cells were significantly better with the NAB approach, the non-NAB approach, in contrast, led to a regulated reprogramming of gene expression, and a significant decrease in the expression of Hormad1, a gene associated with immunogenic responses. The reprogramming efficiency by non-NAB approach was influenced by exosomes present in conditioned medium. Cells reprogrammed by both approaches were capable of differentiating along the three germ lineages and generating chimeras. The analysis suggests that both approaches are effective in reprogramming limbal progenitors but the non-NAB approach may be more suitable for potential clinical applications by averting the risk of insertional mutagenesis and immune responses associated with the NAB approach.

Analysis of a thin film dielectric characterization method based on the impedance difference of two MIM capacitors (2017)

This paper presents an analysis of a thin film dielectric characterization method based on the impedance difference of two circular capacitors. For the first time, an error study is detailed in order to define what the best case to use the method is. To illustrate the study, the method has been applied for two dielectrics with extremely different RF properties: silicon nitride (low permittivity and low loss tangent) and Barium Calcium Zirconate Titanate (very high permittivity and high loss tangent).
Symbol-by-symbol MAP decoding algorithm for high-rate convolutional codes that use reciprocal dual codes (1998)

A symbol-by-symbol maximum a posteriori (MAP) decoding algorithm for high-rate convolutional codes applying reciprocal dual convolutional codes is presented. The advantage of this approach is a reduction of the computational complexity since the number of codewords to consider is decreased. All requirements for iterative decoding schemes are fulfilled. Since tail-biting convolutional codes are equivalent to quasi-cyclic block codes, the decoding algorithm for truncated or terminated convolutional codes is modified to obtain a soft-in/soft-out decoder for high-rate quasi-cyclic block codes which also uses the dual code because of complexity reasons. Additionally, quasi-cyclic block codes are investigated as component codes for parallel concatenation. Simulation results obtained by iterative decoding are compared with union bounds for maximum likelihood decoding. The results of a search for high-rate quasi-cyclic block codes are given in the appendix.
Synchronous Transformers for End-to-End Speech Recognition (2019)

For most of the attention-based sequence-to-sequence models, the decoder predicts the output sequence conditioned on the entire input sequence processed by the encoder. The asynchronous problem between the encoding and decoding makes these models difficult to be applied for online speech recognition. In this paper, we propose a model named synchronous transformer to address this problem, which can predict the output sequence chunk by chunk. Once a fixed-length chunk of the input sequence is processed by the encoder, the decoder begins to predict symbols immediately. During training, a forward-backward algorithm is introduced to optimize all the possible alignment paths. Our model is evaluated on a Mandarin dataset AISHELL-1. The experiments show that the synchronous transformer is able to perform encoding and decoding synchronously, and achieves a character error rate of 8.91% on the test set.
