Effect of Electrolyte Additives on Li4Ti5O12Cycling Performance and Gas Evolution (2018)

Batteries consisting of Li 4 Ti 5 O 12 (LTO) anodes do not require the formation of a solid electrolyte interface to deliver robust high-rate performance at room temperature, however performance suffers at elevated temperatures due to gas evolution.Research has linked gas evolution to the instability of the electrolyte on the surface of charged LTO at elevated temperatures.If this is the case, a passivation layer, which prevents the electrolyte from coming into contact with the charged surface of LTO, should inhibit gas evolution.Several classes of electrolyte additives have been investigated in Li 4 Ti 5 O 12 /LiMn 2 O 4 coin cells and pouch cells.ATR-IR and X-ray photoelectron spectroscopy has been used to gain an understanding of the surface films formed with different additives while in-situ gas measurements based on Archimedes' principle and gas chromatography have given insight into how the implementation of these additives affects gassing.The results from this study enable the selective design of surface films for LTO anodes, which reduces gassing at elevated temperatures without sacrificing performance.
Detection of protein-small molecule binding using a self-referencing external cavity laser biosensor (2014)

High throughput screening of protein-small molecule binding interactions using label-free optical biosensors is challenging, as the detected signals are often similar in magnitude to experimental noise. Here, we describe a novel self-referencing external cavity laser (ECL) biosensor approach that achieves high resolution and high sensitivity, while eliminating thermal noise with sub-picometer wavelength accuracy. Using the self-referencing ECL biosensor, we demonstrate detection of binding between small molecules and a variety of immobilized protein targets with binding affinities or inhibition constants in the sub-nanomolar to low micromolar range. The demonstrated ability to perform detection in the presence of several interfering compounds opens the potential for increasing the throughput of the approach. As an example application, we performed a "needle-in-the-haystack" screen for inhibitors against carbonic anhydrase isozyme II (CA II), in which known inhibitors are clearly differentiated from inactive molecules within a compound library.
miRNA Biomarkers in Cyst Fluid Augment the Diagnosis and Management of Pancreatic Cysts (2012)

We found candidate miRNAs that helped identify patients with high-grade IPMN and exclude nonmucinous cysts. These classifiers will require validation in a prospective setting to ultimately confirm their clinical usefulness.
Spontaneous Brillouin-based distributed temperature sensor utilizing a fiber Bragg grating notch filter for the separation of the Brillouin signal (2001)

We report on a Brillouin optical time domain reflectometer-based distributed temperature sensor utilizing a fiber Bragg grating notch filter to suppress the Rayleigh backscatter in order to separate the Brillouin signal. The Brillouin light path is thus subject to minimum attenuation and is frequency independent. A 2-m spatial resolution is achieved over a range of 25 km with the temperature resolution rising from 1/spl deg/C at the near end to 7/spl deg/C at the far end in a measurement time of 10 min. This is reduced to <1/spl deg/C over /spl sim/20 km if the measurement time is increased to 180 min.
Multispectral Imaging Of Burn Wounds (1988)

This research program successfully developed a real-time video imaging system (the Imaging Burn Depth Indicator, or IBDI) which can discriminate areas of burn wounds expected to heal in three weeks or less from the day of injury from those areas not expected to heal in that time period. The analysis can be performed on or about the third day post-burn on debrided burn wounds. Early evaluation of burn healing probability is a crucial factor in the decision to tangentially excise the burn wound. The IBDI measures the reflectivity of the burn wound in the red, green, and near infrared wavelength bands, which data correlate with burn healing probability. The instrument uses an algorithm established in an earlier study to translate the optical data into burn healing probabilities. The IBDI produces two types of images: a true-color image of the burn and a false-color image of the burn. The false-color image consists of up to four colors, each of which indicates a distinct range of probability that the area of the burn so colored will heal within 21 days. Over 100 burn wound sites were studied. Burn sites were evaluated on day three post-burn by our instrument and by the attending physician. Of 55 sites considered to be of intermediate depth, the IBDI predicted the healing outcome accurately in 84% of the cases. By comparison, the predictions of burn surgeons supervising the care of these patients were accurate in 62% of the cases.
Polymerization of secretory IgM in B lymphocytes is prevented by a prior targeting to a degradation pathway. (1992)

B lymphocytes express on their surface a membrane form of IgM (mIgM), and synthesize but fail to secrete a secretory form of IgM (sIgM). Plasma cells shift to the exclusive synthesis and efficient secretion of sIgM. The sIgM in B cells differs from that in plasma cells in its pattern of assembly: in plasma cells, monomers of sIgM are assembled into polymers and only polymers are secreted; in B lymphocytes, monomeric sIgM is neither polymerized nor secreted and is degraded intracellularly. In this article we blocked the export of proteins from the endoplasmic reticulum at low temperatures or with energy poisons or brefeldin A, and localized the different assembly steps of mIgM and sIgM in the 38C B lymphocytes and of sIgM in the 38C-derived sIgM-secreting D2 hybridoma. In both cell lines, sIgM assembly into monomers was not affected, whereas polymerization of sIgM in D2 cells and monomer formation of mIgM in 38C cells were strongly inhibited. Moreover, probing with specific lectins revealed galactosylated monomers and polymers in D2 cells and galactosylated hemimer and monomers only of mIgM in 38C cells. In addition, when Golgi functions were hampered with Tris base, monomerization of mIgM and polymerization of sIgM were attenuated. These results indicate that polymerization of sIgM in D2 cells and monomerization of mIgM in 38C cells are post-endoplasmic reticulum events, occurring in or beyond the trans-Golgi galactosylation compartment. Since only polymers are secreted from D2 cells and only monomeric mIgM is displayed on the surface of 38C cells, partially assembled molecules may traverse the secretory pathway yet are restricted from the cell surface. Furthermore, monomeric sIgM in 38C cells is never galactosylated, thus it is degraded prior to the galactosylation compartment. We conclude that targeting of sIgM to degradation in 38C cells precedes its assembly site into polymers in D2 cells. This implies that degradation of sIgM does not result from the incompetence of 38C cells to polymerize. Rather, assembly of sIgM into polymers and their subsequent secretion are prevented in B lymphocytes by preceding targeting of monomeric sIgM to degradation.
Diversity order in ISI channels with single-carrier frequency-domain equalizers (2010)

This paper analyzes the diversity gain achieved by single-carrier frequency-domain equalizers (SC-FDE) in frequency selective channels, and uncovers the interplay between diversity gain d, channel memory length ¿, transmission block length L, and the spectral efficiency R. We specifically show that for the class of minimum mean-square error (MMSE) SCFDE receivers, for rates R ¿ log L/¿ full diversity of d = ¿+ 1 is achievable, while for higher rates the diversity is given by d = [2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-R</sup> L + 1. In other words, the achievable diversity gain depends not only on the channel memory length, but also on the desired spectral efficiency and the transmission block length. A similar analysis reveals that for zero forcing SC-FDE, the diversity order is always one irrespective of channel memory length and spectral efficiency. These results are supported by simulations.

Avtal om funktionsförsäljning som kreditsäkerhet : En analys kring funktionsförsäljning de lege ferenda (2019)

Denna uppsats behandlar en ganska okänd affärsmodell, funktionsförsäljning, men vilken är på frammarsch och kan komma att bli allt viktigare i och med den nödvändiga klimatomställning som behöver göras på jorden. Funktionsförsäljning anses bidra till lägre resursförbrukning och affärsmodellen kan bidra till nya möjligheter inom ekonomin. Den fråga som behandlas i uppsatsen är huruvida ett funktionsavtal kan användas som kreditsäkerhet för funktionssäljarens krediter. Frågan besvaras genom en utredning av tillgängliga kreditsäkerhetsformer däribland, skuldebrev, växel, företagshypotek och handpant. Det framkommer att köparens invändningsrätt mot säljaren är det som i stor utsträckning är avgörande för huruvida ett kreditinstitut beviljar en borgenär kredit med köpavtal som säkerhet, dvs factoring. Funktionsförsäljning har emellertid egenskaper som köp av varor och tjänster saknar i och med förekomsten av lös egendom som används för att tillhandahålla en funktion hos köparen. Den hos köparen installerade egendomen torde enligt analysen kunna användas som säkerhet hos köparen i utbyte mot att köparen utställer en växel gentemot funktionssäljarens borgenär. Köparen kan då inte göra gällande invändningar, rörande det bakomliggande funktionsavtalet, mot betalningskrav från växelborgenären. Funktionsavtal löper såsom ett abonnemang och det är de framtida betalningarna från köparen som funktionssäljarens borgenär i så fall övertar och därför beviljar kredit till funktionssäljaren. En förutsättning för ett sådant upplägg är att egendomens värde motsvarar köparens värde av invändningsrätt gentemot fordringsägaren. Vidare framhålls att konsumenttjänstlagen bör vara tillämplig på funktionsförsäljning i nu gällande rätt. Ett exempel på funktionsavtal har upprättats som en bilaga och kring det avtalet har vissa begränsningar i konsumenttjänstlagen och närliggande lagar diskuterats rörande funktionsförsäljning. I slutsatsen läggs fram att nuvarande reglering bör ses över i det fall det är önskvärt att gynna aktörerna som funktionsförsäljning som en ny affärsmodell i samhället för både miljöns och kreditmarknadens skull.
Cooperation of spike timing-dependent and heterosynaptic plasticities in neural networks: A Fokker-Planck approach (2006)

It is believed that both Hebbian and homeostatic mechanisms are essential in neural learning. While Hebbian plasticity selectively modifies synaptic connectivity according to activity experienced, homeostatic plasticity constrains this change so that neural activity is always within reasonable physiological limits. Recent experiments reveal spike timing-dependent plasticity (STDP) as a new type of Hebbian learning with high time precision and heterosynaptic plasticity (HSP) as a new homeostatic mechanism acting directly on synapses. Here, we study the effect of STDP and HSP on randomly connected neural networks. Despite the reported successes of STDP to account for neural activities at the single-cell level, we find that, surprisingly, at the network level, networks trained using STDP alone cannot seem to generate realistic neural activities. For instance, STDP would stipulate that past sensory experience be maintained forever if it is no longer activated. To overcome this difficulty, motivated by the fact that HSP can induce strong competition between sensory experiences, we propose a biophysically plausible learning rule by combining STDP and HSP. Based on the Fokker-Planck theory and extensive numerical computations, we demonstrate that HSP and STDP operated on different time scales can complement each other, resulting in more realistic network activities. Our finding may provide fresh insight into the learning mechanism of the brain.
An overview of business process adaptations via protocols (2006)

Business process management in open environments poses special challenges. In particular, such environments are dynamic, thereby requiring frequent changes in business processes. Current business process modeling approaches handle such changes in an ad hoc manner, and lack a principled means of determining what needs to be changed and where.This paper provides an overview of process adaptability through a novel application of business protocols, especially of protocol composition, introduced in our previous work. Through a real business scenario of auto-insurance claim processing, this paper briefly describes how a wide range of adaptations can be handled naturally and systematically via protocol composition. The illustrated adaptations have been evaluated via a prototype.
Stochastic Geometry Analysis of Hybrid Aerial Terrestrial Networks with mmWave Backhauling (2020)

To best provision the wireless data deluge, service providers are increasingly considering the use of Unmanned aerial vehicles (UAVs) for enhancing wireless connectivity. UAVs are especially important in case of disasters and accidents which may cripple terrestrial networks. In order to maintain the communication of UAVs with the core network, it becomes particularly important to connect UAVs to terrestrial base stations (BSs) via wireless backhaul links. In this work, we use stochastic geometry to study the impact of millimeter-wave (mmWave) backhauling of UAVs in a hybrid aerial-terrestrial cellular network, where the UAVs are added to assist terrestrial BSs in delivering service to users (UEs). In the proposed model, the UE can associate with either a terrestrial BS or a UAV connected to a BS to get backhaul support. The performance of the model is evaluated in terms of coverage probability and validated against intensive simulations. The obtained results unveil that the quality of the UAVs backhaul link has a significant role in improving the UEs experience. The results further illustrate the impact of the different UAVs heights regimes on the coverage probability.
Rigorous analysis of birefringent networks (1986)

Tunable birefringent spectral filters are used in many applications which require narrow transmitted bandwidths with high optical power throughput. A rigorous electromagnetic analysis of bulk birefringent networks will provide the basis for a more complete understanding of these filters and may also lead to new optimal network architectures. A similar rigorous analysis of the folded Sole filter has been previously presented by Yeh. 1 Analyses of other network architectures, particularly multiple-pass birefringent networks, and an explicit discussion of the multiple-beam interference effects are presented.
Corticosteroid Binding Proteins of Liver Cytosol and Interactions with Carcinogens (1971)

The subcellular fates of corticosteroids in liver were studied in a search for a specific biochemical function of the hormone that might be related to its action in stimulating protein synthesis; in particular, the stimulation of activity of enzymes with short half-lives, such as tyrosine aminotransferase (E.C. 2.6.1.5). Separation of subcellular fractions by differential centrifugation [1] and autoradiography [2] revealed that 45 min after intraperitoneal administration, a time when the hormone radioactivity was maximal in liver (Fig. 1) the distribution of cortisol radioactivity was, in the order of concentration: cytosol ≫ microsomal > nuclear > mitochondrial fractions. The peak of accumulation of radioactivity in all of these compartments occurred before there was a measurable increase in tyrosine aminotransferase activity in the cytosol as shown in Fig. 2. Radioactivity from cortisol was concentrated to a maximum by 45 min and declined thereafter, virtually disappearing by 240 min. Significantly, there was a decline in radioactivity in all of the compartments studied, including the nuclear fraction.
Cardiac magnetic resonance perfusion imaging for the functional assessment of coronary artery disease: a comparison with coronary angiography and fractional flow reserve (2006)

In contrast to earlier studies that compared CMRI with morphological examination (CA) alone, the present study compared CMRI with CA plus a standard invasive functional assessment (FFR) and demonstrated that CMRI is able to distinguish haemodynamically relevant from non-relevant coronary lesions with a high sensitivity and specificity and may therefore contribute to clinical decision-making.
On Dense Subgraphs in Signed Network Streams (2016)

Signed networks remain relatively under explored despite the fact that many real networks are of this kind. Here, we study the problem of subgraph density in signed networks and show connections to the event detection task. Notions of density have been used in prior studies on anomaly detection, but all existing methods have been developed for unsigned networks. We develop the first algorithms for finding dense subgraphs in signed networks using semi-definite programming based rounding. We give rigorous guarantees for our algorithms, and develop a heuristic EGOSCAN which is significantly faster. We evaluate the performance of EGOSCAN for different notions of density, and observe that it performs significantly better than natural adaptations of prior algorithms for unsigned networks. In particular, the improvement in edge density over previous methods is as much as 85% and usually over 50%. These results are consistent across signed and unsigned networks in different domains. The improvement in performance is even more significant for a constrained version of the problem involving finding subgraphs containing a subset of query nodes. We also develop an event detection method for signed and unsigned networks based on subgraph density. We apply this to three different temporal datasets, and show that our method based on EGOSCAN significantly outperforms existing approaches and baseline methods in terms of the precision-recall tradeoff (by as much as 25-50% in some instances).

Plasma enhancement of current from carbon cathodes for field emission displays (1996)

Summary form only given. In this paper, we examine the possibility of using a background gas medium to enhance the current available from low threshold carbon cathodes. The field emission current is used to initiate a plasma in the gas medium, and thereby achieve a current multiplication effect. Results on the variation of anode current as a function of electric field and gas pressure are presented. These are compared with model calculations to verify the principles of operation. The influence of ion bombardment on the long term performance thin film carbon cathodes is examined for He and Ar multiplication plasmas. A measure of the influence of current multiplication on display quality is presented by examining light output from two standard low voltage phosphors. Also studied are the influence of doping the carbon with N to lower the threshold voltage for emission as well as the consequent impact on anode current from the plasma. In addition, microscopic surface roughness of the cathode and its impact on emission properties are examined. The results presented will provide an evaluation of a combined field emission-plasma switching approach to obtain flat panel displays with increased brightness, viewing angle and wider range of operation temperature.
A conversion of aromatic thiocyanates into sulfothioates: new synthetic route to aromatic Bunte salts (2012)

A new synthetic route leading to polysubstituted S-aryl sulfothioates, aromatic Bunte salts, is reported. Treatment of polysubstituted aromatic thiocyanates with sodium sulfite in aqueous DMF at room temperature affords polysubstituted S-(het)aryl sulfothioates. The novel transformation tolerates presence of a wide range of functional groups.
