On the Optimization of Laser-Powered UAV-Assisted Backscatter Communications
Authors: Abdelhady Amr , Diaz-Vilor Carles , Celik Abdulkadir , Jafarkhani Hamid , Eltawil Ahmed 
Published: December 2022

<p>This paper studies the joint trajectory and resource allocation problem for a laser-powered unmanned aerial vehicle (UAV) assisted data aggregation framework. The considered system incorporates semi-passive nodes that establish their wireless communication links with the UAV via bistatic backscatter communications enabled by a battery-powered power beacon source. We aim to optimize the UAV trajectory while minimizing the laser energy consumption throughout the whole flight by tuning the laser power and the power beacon radiated temporal power profiles. Towards this aim, we first adopt path discretization to approximate the optimal control problem of interest into a non-linear programming one whilst accounting for the UAV dynamics constraints and available power budget restrictions. Then, we solve the problem by successive convex approximation (SCA) over the joint set of variables and determine the problem feasibility by a data collection maximization problem. Moreover, we propose a low-complexity solution for the feasibility problem. Finally, the conducted simulations show that the proposed algorithm provides 50% collected data increase and almost 50% laser energy reduction under different operation conditions such as laser station position, maximum laser output power, start and end points of the trajectory, power beacon battery capacity, and the permissible flight length.</p>
Quantum Noise And Measuring Quantum Distance For NISQ Circuits
Authors: Sazzad Sakibul Islam , Nag Protik 
Published: December 2022

<p> In this article, we analyzed the performance of several classes of quantum circuits under various errors. We executed NISQ circuits on both noisy simulator and real hardware backend publicly available from IBM Quantum. On simulation, we created noise models with both individual errors and combination of multiple errors to quantify how each type of error impact performance of quantum circuits. We utilized statistical distances such as total variation distance (TVD), Jensen-Shannon divergence (JSD), and Hellinger distance, to measure the deviation of noisy output from ideal output. Finally, we compare the noisy outputs from the simulator and outputs from the real hardware to showcase the gap between simulation and real device experiment. This gap points to the limitation of present noise models failure to exhibit the behavior of real hardware.</p>

Abstract
After 49 yr of quiescence, 4U 1730–22 became active and had two outbursts in 2021 and 2022; the onset and tail of the outbursts were observed by NICER, which give us a peerless opportunity to study the state transition and its underlying mechanism. In this work, we take both the neutron star (NS) surface and accretion disk emission as the seed photons of the Comptonization and derive their spectral evolution in a bolometric luminosity range of 1%–15% L
Edd. In the high/soft state, the inferred inner disk radius and the NS radius are well consistent, which implies that the accretion disk is close to the NS surface. For the decay stage, we report a steep change of the accretion disk emission within 1 day, i.e., the soft-to-hard transition, which could be due to the propeller effect, and the corresponding NS surface magnetic field is 1.8–2.2 × 108 G. Moreover, the inner disk radius is truncated at the corotation radius, which is similar to the propeller effect detected from 4U 1608–52. The absence of the propeller effect in the hard-to-soft state transition implies that the transition between the magnetospheric accretion and the disk accretion is not the sole cause of the state transitions.
Compétences pour télécollaborer dans un environnement plurilingue : référentiel et tâche
Authors: Chachkine Elsa , Salengros-Iguenane Isabelle 
Published: December 2022

Dans cet article, nous proposons un référentiel des compétences pour télécollaborer dans un environnement plurilingue. Les enseignants de langues du supérieur peuvent s'y référer pour préparer les étudiants à télécollaborer, en mobilisant des pratiques plurilingues et en s'appuyant sur des ressources numériques. Le référentiel que nous avons conçu s'ancre dans une conception humaniste de la formation (Allport et al., 1971 ; Ryan & Deci, 2017). Plus précisément, nous plaçons la compétence à collaborer à distance (Henri & Lundgren-Cayrol, 2003 ; Daele & Charlier, 2006) au centre de la compétence à télécollaborer. Les littératies numériques (Ollivier et al., 2018) et les pratiques plurilingues (Carap, 2012 ; Refic, 2019) complètent le référentiel de compétences. Un exemple de tâche en FLE, qui prend appui sur le référentiel, est proposé. La tâche est destinée à des élèves ingénieurs et des doctorants de deux établissements d'enseignement supérieurs français.
Aspergillus fumigatus–Secreted Alkaline Protease 1 Mediates Airways Hyperresponsiveness in Severe Asthma

Abstract
The hallmark features of allergic asthma are type 2 (eosinophilic) inflammation and airways hyperresponsiveness (AHR). Although these features often comanifest in mouse lungs in vivo, we demonstrate in this study that the serine protease Alp1 from the ubiquitous mold and allergen, Aspergillus fumigatus, can induce AHR in mice unable to generate eosinophilic inflammation. Strikingly, Alp1 induced AHR in mice devoid of protease-activated receptor 2/F2 trypsin-like receptor 1 (PAR2/F2RL1), a receptor expressed in lung epithelium that is critical for allergic responses to protease-containing allergens. Instead, using precision-cut lung slices and human airway smooth muscle cells, we demonstrate that Alp1 directly increased contractile force. Taken together, these findings suggest that Alp1 induces bronchoconstriction through mechanisms that are largely independent of allergic inflammation and point to a new target for direct intervention of fungal-associated asthma.
Further Experiences with the Isolated Organ Lipoids As “Antigen” in the Wassermann Test
Authors: L'Esperance Elise S. , Coca Arthur F. 
Published: December 2022

Abstract
Our previous publications (1) upon the Wassermann reaction have dealt chiefly with the technique of the test. We have called attention to two important sources of error that attach to the use of the isolated organ lipoids (Noguchi) as “antigen.” These were: first, the non-specific or “pseudo-reaction” that is sometimes obtained with the originally prescribed quantity of “antigen” when the serum to be tested has not been heated; and secondly, the prezone phenomenon of wanting or weak reaction, which sometimes occurs with positively reacting sera where the larger quantities of the lipoid emulsion are used.
In a subsequent larger series of examinations we have not only confirmed those observations, but, through our association with Dr. E. L. Keyes and with the generous assistance of Dr. D. W. MacKenzie, Dr. B. S. Barringer and Dr. J. D. Kernan, Jr., we have been able, also, to reach a definite conclusion as to the relative clinical efficiency of our technical method in the diagnosis of syphilis.
Is the Hyperleucocytosis Following the Injection of Typhoid Bacilli Into Immunized Rabbits Specific?
Authors: McWilliams Helen I. 
Published: December 2022

Abstract
There is an extensive literature presenting experiments designed to show that the leucocytes play a more active part in ridding the organism of injected bacteria in immunized animals than in normal ones. This qualitative response on the part of the leucocytes has been very carefully studied and is specific. Gay and Claypole (1) have, however, recently described a quantitative response in the leucocytes of immunized animals which they claim is also specific. Upon injecting a normal rabbit intravenously with typhoid bacilli there results first a leucopenia and then a hyperleucocytosis; if a rabbit immunized against typhoid bacilli is similarly injected, they found likewise first a leucopenia and then a hyperleucocytosis, but the hyperleucocytosis in this case was much greater in degree than that called forth in the normal animal. Their table indicates that normal rabbits will show a maximum of about 35,000 to 60,000 leucocytes to the cubic millimeter, while the rabbits immunized against typhoid bacilli yield counts of 60,000 to 150,000.
Studies in Specific Hypersensitiveness

Summary
The removal of all protein and other detectable nitrogenous substances from pollen and house dust extracts, by means of tryptic digestion and dialysis, causes no appreciable lessening of the atopic activity of the extracts.
These atopens seem, therefore, not to be proteins, in the usual sense.
The tryptic digestion of the proteins of horse dander and of green pea causes a diminution of atopic activity, corresponding with the loss of protein by the digestion.
The atopens of horse dander and of green pea appear, thus, to be of protein nature.

Summary
Studies of the pollen antigens have resulted in the following conclusions: Timothy and ragweed pollens have definite antigenic properties and may induce in the uinea-pig a condition of hyper-sensitiveness; intravenous injection of the specific antigen in such animals can result in death by acute or delayed anaphylactic shock.With the Dale and intravenous testing methods as criteria, comparison of the states of sensitivity induced by injections of the pollen extracts and by “border zone” doses of an immune egg-white serum indicates that: The pollen antigen sensitizes a much smaller number of animals.The pollen antigen induces a state of maximal or acute sensitivity in a smaller percentage of animals.The contraction of the pollen-sensitive uterus tends to be slower in starting, and it is more irregular than is the contraction of the egg-white sensitive uterus.Pollen sensitivity is specific, except against related pollens of the same family.Passive transfer of sensitivity was accomplished in only one animal with only partial success, the sensitivity induced being detected by the Dale method, but not by the intravenous test.The pollen antigen-antibody reaction is much more time consuming than that of egg-white, both in vivo and in vitro.The presence of precipitins has not been demonstrated in the sera of any of the pollen sensitive animals.The rules of Coca and Kosakai for precipitin neutralization are not applicable to the pollen antigen-antibody reaction.Digestion with trypsin and dialysis does not remove the active antigenic principle of ragweed pollen.The non-digestible, non-dialyzable factor is common to both high and low ragweed pollens, and is almost as strongly antigenic as the whole pollen. (This factor seems, thus, to be the same principle which Coca and Grove found to be the atopen in ragweed hay fever.)Beside the non-digestible and non-dialyzable factor, there are one or more less important antigens in ragweed, probably protein in nature.

Abstract
In a former publication (1) on this topic, it was stated that while the methods described in that publication provided preparations capable of successful diagnostic and therapeutic use, the problem was still under investigation. Most of the methods have been under constant study, and have been subjected to more or less important changes. The chief objects of the study were: First, to lessen the deterioration to which a number of the materials are subject; second, to effect a needed concentration of the active substances in some of the preparations; and, third, to simplify and facilitate the technical aspects of the methods.
General Considerations. The various active substances responsible as exciting agents of atopic conditions are not all of the same nature. Studies carried out in this organization have shown that the atopens of pollens and of house dust and orris root are “non-protein” substances, whereas that of horse dander is at least in part a digestible protein.
