A novel interference-aware, optimal gain adaptation policy for a non-regenerative, underlay cognitive radio relay (2014)

A relay that operates in an underlay cognitive radio (CR) system is subject to tight constraints on the interference its transmissions cause to the primary receiver (P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Rx</sub> ). While several appealing non-regenerative amplify-and-forward (AF) relaying schemes have been proposed for underlay CR, they are simple, ad hoc adaptations of conventional AF relaying schemes. We present a novel and optimal relay gain adaptation policy (ORGAP) in which the interference-aware relay optimally adapts its gain as a function of its local channel gains. It minimizes the symbol error probability (SEP) at the secondary receiver subject to a constraint on the average interference caused to the P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Rx</sub> . We also analyze the SEP of MPSK of ORGAP, which serves as a fundamental theoretical benchmark for the gains achievable by AF relaying in CR systems. Extensive numerical results quantify the extent to which ORGAP outperforms several known conventional AF relaying schemes. We also present a near-optimal, simpler relay gain adaptation policy (SRGAP) that is easier to implement.
Monoclonal Antibodies — A Different Approach to Combat Malaria (2022)

In 2020, a total of 241 million cases of malaria and 627,000 malaria-related deaths were reported.1 In this issue of the Journal, Wu and colleagues2 present a new approach to provide immune protection with a next-generation monoclonal antibody against Plasmodium falciparum malaria infection, the most prevalent and deadly type of malaria. Therapeutic monoclonal antibodies target a specific antigen, provide high specificity and safety, and are routinely used in medical practice to treat cancer and autoimmune diseases, and recently they have been used to prevent Covid-19.3,4 Wu et al. conducted VRC 614, a phase 1 clinical trial to test the safety, . . .

Multicystic demyelinating myelopathy (2014)

A 10-year-old girl presented with subacute lower limb weakness and gait ataxia. MRI revealed a large multicystic spinal cord lesion with patchy enhancement (figure 1, A and B) and 3 small (<6 mm) periventricular and deep white matter brain lesions. The presence of serum anti-aquaporin-4 (AQP4) immunoglobulin G (ELISA assay) and compatible neuropathologic features from neurosurgical specimens1 (figure 2) suggested the diagnosis of a neuromyelitis optica spectrum disorder.2 Targeted immunotherapy was started, with partial lesion resolution (figure 1C).

Conception d'algorithmes répartis et de protocoles réseaux en approche objet (1997)

Streptomyces viridochromogenes Tü494 produces the herbicide phosphinothricyl-alanyl-alanine (phosphinothricin-tripeptide=PTT; bialaphos). Its bioactive moiety phosphinothricin competitively inhibits bacterial and plant glutamine synthetases. The biosynthesis of PTT includes the synthesis of the unusual amino acid N-acetyl-demethyl-phosphinothricin and a three step condensation via non-ribosomal peptide synthetases. Two characteristics within the PTT biosynthesis make it suitable to study the evolution of secondary metabolism biosynthesis. First, PTT biosynthesis represents the only known system where all peptide synthetase modules are located on separate proteins. This 'single enzyme system' might be an archetype of the multimodular and multienzymatic non-ribosomal peptide synthetases in evolutionary terms. The second interesting feature of PTT biosynthesis is the pathway-specific aconitase Pmi that is involved in the supply of N-acetyl-demethyl-phosphinothricin. Pmi is highly similar to the tricarboxylic acid aconitase AcnA. They share 64% identity at the DNA level and both belong to the Iron-Regulatory-Protein/AcnA family. Despite their high sequence similarity, AcnA and Pmi catalyze different reactions and are not able to substitute for each other. Thus, the enzyme pair AcnA/Pmi presents an example of the evolution of a secondary metabolite-specific enzyme from a primary metabolism enzyme.
Late Urinary Bladder Metastases after Radical Resection of Prostatic Carcinoma (1994)

The case of a 69-year-old man who underwent radical prostatectomy because of carcinoma of the prostate is reported. A preoperative cystoscopy was normal. The histological evaluation of the radical prostatectomy showed an infiltration of the urethral margin. 14 months later, cystoscopy showed papillary metastases of the prostatic carcinoma in the bladder. Immunohistochemistry and flow cytometry for various prognostic factors showed a high malignant potential of this tumor. Preoperative transurethral instrumentation for the treatment of urethral strictures may be responsible for the dissemination of tumor cells into the bladder.

Ingestion of Plasmodium Falciparum Sporozoites during Transmission by Anopheline Mosquitoes (1992)

We investigated the process of sporozoite transmission during blood feeding for Anopheles gambiae and An. stephensi experimentally infected with Plasmodium falciparum. When infective mosquitoes were fed 22-25 days postinfection on an anesthetized rat, sporozoites were detected in the midgut of 96.5% of 57 An. gambiae (geometric mean [GM] = 32.5, range 3-374) and in 96.2% of 26 An. stephensi (GM = 19.5, range 1-345). There were no significant differences between species either in salivary gland sporozoite loads or in the number of ingested sporozoites. There was a significant linear relationship between sporozoite loads and the numbers of ingested sporozoites for both An. gambiae (r = 0.38) and An. stephensi (r = 0.69). Subsequently, An. gambiae were tested for sporozoite transmission by allowing them to feed individually on a suspended capillary tube containing 10 microliters of blood. A total of 83.3% of 18 infective mosquitoes transmitted a GM of 5.9 (range 1-36) sporozoites. The same mosquitoes contained a GM of 23.4 (range 2-165) ingested sporozoites. The number of ingested sporozoites was related to sporozoite loads (r = 0.42) but not to the number of sporozoites ejected into capillary tubes. Ingested sporozoites remained in the midgut up to 10 hr after feeding. The comparable numbers of sporozoites ingested by infective mosquitoes in both experiments indicates that the actual number of sporozoites transmitted to the vertebrate host during blood feeding is significantly reduced by the blood ingestion process.(ABSTRACT TRUNCATED AT 250 WORDS)

Orbital Angular Momentum (OAM) based Mode Division Multiplexing (MDM) over a Km-length Fiber (2012)

We demonstrate the first MDM scheme using OAM states over 1.1-km of fiber. This is enabled by a SLM-based Mux/Demux setup, and a fiber designed to propagate multiple OAM modes over km lengths. We confirm low crosstalk (&lt;−14.8dB) and multipath interference (&lt;−19.7dB) of this scheme by transmitting 400Gb/s QPSK data at 1550nm without MIMO processing.
Characterization of Titanium Dioxide Blocking Layers in Dye-Sensitized Nanocrystalline Solar Cells (2003)

The properties of thin blocking layers of titanium dioxide used to improve the performance of dye-sensitized nanocrystalline solar cells have been studied. TiO2 blocking layers prepared on fluorine-doped tin oxide-coated glass by spray pyrolysis have been characterized by electrochemical impedance spectroscopy, spectroscopic ellipsometry, and voltammetry. The impedance data reveal the presence of a distribution of surface states at the titanium dioxide−electrolyte interface that is similar to the one seen in the case of nanocrystalline TiO2 films. The influence of the blocking layers on the back transfer of electrons to tri-iodide ions in electrolyte-based dye-sensitized nanocrystalline cells has been studied by open circuit photovoltage decay. The results show that the ability of the blocking layer to prevent the back reaction of electrons with tri-iodide ions in the electrolyte is excellent under short circuit conditions, but is limited under open circuit conditions by electron accumulation at the surface of the titanium dioxide blocking layer.
A sub-400 fJ/bit thermal tuner for optical resonant ring modulators in 40 nm CMOS (2012)

Optical ring modulators are highly susceptible to external temperature noise and to self-heating from absorbed optical power. We mitigate both problems through circuit techniques. A control loop at the ring measures output power and controls a local heater to compensate for external temperature noise. A control loop at the receiver dynamically tracks DC variations to compensate for self-heating effects. The design has been implemented in a 40 nm TSMC technology.
An Evaluation of the Impact of Visual Embellishments in Bar Charts (2015)

Abstract As data visualization becomes further intertwined with the field of graphic design and information graphics, small graphical alterations are made to many common chart formats. Despite the growing prevalence of these embellishments, their effects on communication of the charts’ data is unknown. From an overview of the design space, we have outlined some of the common embellishments that are made to bar charts. We have studied the effects of these chart embellishments on the communication of the charts’ data through a series of user studies on Amazon's Mechanical Turk platform. The results of these studies lead to a better understanding of how each chart type is perceived, and help provide guiding principles for the graphic design of charts.
Pertussis Toxin composite nanofibers as a non-invasive whooping cough vaccine (2007)

Global resurgence of whooping cough, a highly contagious disease caused by the fastidious gram negative coccobacillus, Bordetella pertussis, has raised questions of the current preventative and treatment technologies. A novel non-invasive vaccine has been developed by immobilization of Pertussis Toxin (PT) in electrospun polymer (Polyvinylpyrrolidone, PVP) nanofibers. In vitro experiments were utilized to test the bioavailability of PT inside of electrospun fibers. The sensitive assay for PT employs Chinese Hamster Ovary (CHO) cells. CHO cells, which form an attached monolayer in their native environment, undergo clumping in the presence of PT. The assay qualitatively measured clumping in the presence of native PT and dissolved PT-PVP electrospun coating for varied concentrations of CHO cells. Microscopic observation showed clumping with a sensitivity of 2.5 ng/ml of dissolved electrospun coating at 48 hours. The results of the in vitro assay confirm retention of biological activity of PT in electrospun nanofibers. This provides a means to develop a dermal pathway for a more effective long-term immunity against whooping cough. The application of electrospun coating can provide dermally-transferred immunity against other infectious diseases, thus overtaking oral or injectable vaccines.
Performance of a hardware-assisted real-time garbage collector (1994)

Hardware-assisted real-time garbage collection offers high throughput and small worst-case bounds on the times required to allocate dynamic objects and to access the memory contained within previously allocated objects. Whether the proposed technology is cost effective depends on various choices between configuration alternatives. This paper reports the performance of several different configurations of the hardware-assisted real-time garbage collection system subjected to several different workloads. Reported measurements demonstrate that hardware-assisted real-time garbage collection is a viable alternative to traditional explicit memory management techniques, even for low-level languages like C++.
Structure and state of water in reversed aerosol OT micelles: an infrared study (2007)

The structure of water in bis(2-ethylhexyl)sodium sulfosuccinate (AOT) micelles has been studied as a function of the [H2O]/[AOT] ratio (W) by using the absorption IR due to O-H stretching modes in the 3800–3000 cm−1 range. Two systems have been studied: water/AOT/carbon tetrachloride and water/AOT/n-heptane. The results show that IR spectra can be expressed as sum of contributions from interfacial and bulklike water. The fraction of water in the two “regions” within the water pool was evaluated as a function of W. From the data it appears that a continuous variation in the water properties inside micellar cores occurs rather than a two step hydration mechanism. The solubilization of water is described in terms of hydration of the AOT head group and Na+ counterions. The maximum hydration number of AOT was found to be 3 both in CCl4 and n-heptane.
Factors affecting outcomes of individualised treatment for drug resistant tuberculosis in an endemic region> (2017)

<b>Background:</b> Individualised treatment regimens for drug resistant tuberculosis (TB) have improved outcomes. This retrospective observational study examined factors that affect individualised treatment in an endemic region and highlighted predictors of a successful outcome. <b>Methods:</b> We examined records of proven multidrug resistant (MDR), pre-extensively drug resistant (pre-XDR) and XDR TB patients diagnosed and started on treatment between 2010 and 2014, collecting the following data for each patient: age, gender, comorbidities, past history of TB, diagnosis, site of disease, drug susceptibility testing (DST) results, treatment, adverse reactions to anti-tuberculosis drugs, treatment changes and outcomes, which were recorded as positive, negative or neutral. The 2011 WHO drug classification was followed as patients were treated based on these guidelines. Tests of association were carried out between factors and outcomes. Multiple logistic regression analysis was done to determine the predictors of a positive outcome. <b>Results:</b> Fifty-nine patients completed treatment at our centre. The median age was 26 years (range 8–65 years). There were 31 (52.5%) female patients. Forty-four (74.6%) were successfully treated over a median treatment period of 23 months (range 18–30 months). Successful outcomes were associated with age less than 45 years (P = 0.01, OR = 6.67, 95% CI = 1.73-23.47), resistance to fewer than five drugs (P = 0.001, OR = 9.51, 95% CI = 2.50–38.18) and susceptibility to Group 4 drugs (P = 0.04, OR = 4.71, 95% CI = 1.03–16.83). <b>Conclusions:</b> Age less than 45 years and resistance to fewer than five drugs were important predictors of a successful treatment outcome.
Indoor Household Particulate Matter Measurements Using a Network of Low-cost Sensors (2019)

The World Health Organization estimates that 4.3 million deaths globally in 2012 were attributable to household air pollution, of which particulate matter (PM) with a diameter of 2.5 µm or less (PM2.5) is a significant contributor. When integrated with a wireless network, low-cost PM measurements potentially provide personalized information on indoor concentrations in real time so that individuals can take action. The objectives of this study were to (1) deploy a network of research-grade instruments and low-cost sensors in a home environment and evaluate the performance, (2) characterize activities and conditions that increase PM concentrations, and (3) identify how these activities affect the PM levels in different rooms of a home. The wireless sensor network included low-cost PM sensors, a gateway, and a database for storing data. Based on the commercially available Dylos DC1100 Pro (Utah Modified Dylos Sensor) and Plantower PMS sensor (AirU), the low-cost sensors were compared to three research-grade instruments—the GRIMM, DustTrak, and MiniVol—in two households in Salt Lake City during summer and winter, with the results suggesting that the low-cost sensors agreed well with the DustTrak. Of the activities, frying food and spraying aerosol products generated the largest increase in PM, both in the room of the activity (the kitchen and bedroom, respectively) and the adjacent rooms. High outdoor PM concentrations during a cold air pool episode also caused indoor levels to rise. In addition, different PM sources triggered different sensor responses. Consequently, obtaining accurate estimates of the mass concentration in an indoor environment, with its wide variety of PM sources, is challenging. However, low-cost PM sensors can be incorporated into an indoor air-quality measurement network to help individuals manage their personal exposure.
Training Beam Sequence Optimization for Millimeter Wave MIMO Tracking Systems (2018)

In this paper, we consider the design of training beam sequence for sparse millimeter wave (mmWave) multiple-input multiple-output (MIMO) tracking systems. We use Markov random walks to model the temporal variations of the beam steering angle of arrival (AoA) and angle of departure (AoD), respectively. By exploiting the MIMO virtual channel representation, the AoA/AoD tracking problem is equivalent to choosing a set of directional training beams to find the nonzero elements in a two-dimensional virtual channel matrix. Furthermore, in contrast to existing work that used each transmitting-receiving beam pair once only, we consider a more general case such that each beam pair might be adopted more than once in the tracking procedure. As the number of repetitions of each transmitting-receiving beam pair can only be integer, the training beam sequence design problem is then formulated as an integer nonlinear programming (INLP) problem. To resolve the formulated INLP problem, we derive a tractable lower bound of the successful tracking probability and then decompose it into a set of convex INLP subproblems, which are solved by implementing an iterative branch-and-bound (BB) method. Numerical results show that our proposed iterative BB algorithm significantly outperforms the benchmark schemes and achieves near-optimal tracking performance.
