A 6-18GHz 6-bit Phase Shifter for Broadband Phased Array Applications

This paper presents a 6-18-GHz 6-bit broadband phase shifter (PS), which includes six stages. In order to acquire high phase shift resolution, broad bandwidth and small chip area, some different structures were used: (1)the switched-transmission-line structure was used to realize 5.625° phase shift. (2)the high-pass/low-pass filter structure was used to realize the 11.25°, 22.5° and 44.5° phase shifts. (3) the magnetically coupled all-pass network structure was used to realize 90° phase shift. (4)the lange-based structure was used to realize 180° phase shift. The phase shifter was designed in a 0.13-μm SiGe BiCMOS technology. The test results show that, the 6-bit phase shifter has a RMS error <4.3° and a insertion loss variation is ± 1dB at 6–18 GHz. The proposed 6-bit phase shifter achieves a high phase resolution with a broad band width. The core die occupies an area of 3.7mm ×1.2mm and consumes only 0.1 mA from a 1.8-V supply.
Execution Recording and Reconstruction for Detecting Information Flows in Android Apps

Security researchers utilize taint analyses to uncover suspicious behaviors in Android apps. Current static taint analyzers cannot handle ICC, reflection, and lifecycles dependably, increasing the result verification cost. On the other hand, current dynamic taint trackers accurately detect execution paths. However, they depend on specific Android versions and modified devices, reducing their usability and applicability. In addition, they require app exercise every time running the taint analysis. This paper presents a new dynamic taint tracker called T-Recs, tracking information flows by recording and reconstructing the app execution. First, before the taint analysis, the app’s runtime data are obtained by instrumenting logging code into the app’s bytecode and running the app to be independent of specific Android versions and devices. Then, T-Recs performs the taint analysis accurately with the logged data and separately from the app exercise. This paper is an extended version of our work published. Previously, T-Recs’ accuracy was mainly evaluated in privacy leak detection. The results show that T-Recs outperforms compared analyzers, which are FlowDroid (w/ and w/o IC3), Amandroid, DroidSafe, and TaintDroid (w/ and w/o IntelliDroid). This paper also involves DroidRA and IccTA. This paper shows that T-Recs detects ICC- and reflection-related leaks missed by FlowDroid in popular Google Play apps. The other static analyzers fail to analyze most of the apps. These experiments also indicate an advantage of T-Recs: its users can re-execute T-Recs’ taint analysis without re-exercising the app. T-Recs’ app-runtime overhead and parallel execution performance were also evaluated, and the results are acceptable.
An algorithm for solving nonlinear resistor networks

This article describes an algorithm for solving electrical networks which consist of linear and nonlinear resistors and independent sources, and where the characteristics of each of the resistors is described by a function G k (.), i e G k (v), where G k (.) is continuous, monotonically increasing, piece-wise linear, and one-to-one from (− ∞, ∞) onto (− ∞, ∞), and where k is an index which spans all the resistors in the network. The solution is found by solving successively equivalent linear networks which represent the nonlinear network locally and which correspond to a “solution curve. ” Essential to the efficiency of the computation process is the method of modifying matrices which enables the process to find the inverse of a conductance matrix by modifying another matrix rather than by matrix inversion. The algorithm provides a fast computation method for both of the following two cases: (1.) the network contains both linear and nonlinear resistors and (2.) the sources are functions of time and the solution is required for successive values of time. In the latter case the algorithm computes each solution from the previous one rather than solving each case independently.
Blue Stragglers and Other Stellar Anomalies: Implications for the Dynamics of Globular Clusters

There are several observed phenomena in globular clusters that are thought to be the result of dynamical processes or binary star evolution. This review examines these manifestations of the interaction between globular cluster dynamics and stellar evolution. Blue stragglers may be formed by the evolution of primordial binaries or by collisions. Current evidence suggests that both processes are likely to occur, and that the observed blue straggler sequences can place dynamically interesting limits on rates. Color gradients in globular clusters are thought to be caused by the stripping of giants by collisions, although the creation of blue subdwarfs by the same process may also be required to explain the observations. The observed X-ray sources and radio pulsars are apparently also made by a variety of dynamical processes that are still not fully understood.
On the Neural Network Technologies Application in Diagnosing of the IT-Structure Element Base

The article discusses the idea obtaining diagnostic information of the element base with the IT-structure decomposition. A preliminary sorting of the components of the element base according to the technical condition is organizing network technologies to improve the reliability of IT-structures. A classification and sorting of components according to their technical condition in the MATLAB-environment is proposed.
Biodegradable Microcapsules of Poly(Butylene Adipate-co-Terephthalate) (PBAT) as Isocyanate Carriers and the Effect of the Process Parameters

Poly(butylene adipate-co-terephthalate) (PBAT), a biodegradable flexible, and tough polymer is herein used, for the first time, to encapsulate and protect isocyanate derivatives. Isocyanates are essential building blocks widely employed in the chemical industry for the production of high-performing materials. Microencapsulation of isocyanates eliminates the risks associated with their direct handling and protects them from moisture. In light of this, and having in mind eco-innovative products and sustainability, we present a straightforward process to encapsulate isophorone diisocyanate (IPDI) using this biodegradable polymer. Spherical and core-shell microcapsules (MCs) were produced by an emulsion system combined with the solvent evaporation method. The MCs present a regular surface, without holes or cracks, with a thin shell and high isocyanate loadings, up to 79 wt%. Additionally, the MCs showed very good isocyanate protection if not dispersed in organic or aqueous solutions. Effects of various process parameters were systematically studied, showing that a higher stirring speed (1000 rpm) and emulsifier amount (2.5 g), as well as a smaller PBAT amount (1.60 g), lead to smaller MCs and narrower size distribution.
An Electromagnetic Method for Transducing Jaw Movements during Speech

A new method for transducing movements of the mandible is described. The equipment employed includes a three‐coil magnetometer system that enables real‐time recording of jaw movements without encumbrance to natural articulation. Theoretical principles underlying the method are discussed, as are procedures for using and calibrating the equipment. Examples of one‐ and two‐dimensional measurements are presented, the latter being related to displacement pathways followed during nonspeech gestures of the mandible. Beyond the specific method described, it is concluded that magnetometers have attractive potential as a research tool in speech physiology.
Quantification of Lung Tumor Motion and Optimization of Treatment

Background: Mobility of lung tumors is induced by respiration and causes inadequate dose coverage. Objective: This study quantified lung tumor motion, velocity, and stability for small (≤5 cm) and large (>5 cm) tumors to adapt radiation therapy techniques for lung cancer patients. Material and Methods: In this retrospective study, 70 patients with lung cancer were included that 50 and 20 patients had a small and large gross tumor volume (GTV). To quantify the tumor motion and velocity in the upper lobe (UL) and lower lobe (LL) for the central region (CR) and a peripheral region (PR), the GTV was contoured in all ten respiratory phases, using 4D-CT. Results: The amplitude of tumor motion was greater in the LL, with motion in the superior-inferior (SI) direction compared to the UL, with an elliptical motion for small and large tumors. Tumor motion was greater in the CR, rather than in the PR, by 63% and 49% in the UL compared to 50% and 38% in the LL, for the left and right lung. The maximum tumor velocity for a small GTV was 44.1 mm/s in the LL (CR), decreased to 4 mm/s for both ULs (PR), and a large GTV ranged from 0.4 to 9.4 mm/s. Conclusion: The tumor motion and velocity depend on the tumor localization and the greater motion was in the CR for both lobes due to heart contribution. The tumor velocity and stability can help select the best technique for motion management during radiation therapy.
Rellis Coded Modulation Over Partial Response Fading Channels

In this paper we present a framework on Trellis Coded Modulation (TCM) over a new channel model, denoted as 1+ D Partial Response Fading Channel (PRFC). To reduce the channel effect on signal we used a precoder before sending signal to channel. This precoder does not increase the number of states in trellis diagram it is only use to cancel the partial response effect of the channel. We use a rate of 2/3 encoder and 8 PSK as modulation scheme. We evaluated performance of TCM over PRFC for different Rican fading parameters K and signal-to-noise ratios(SNR). KeywordsTrellis Coded Modulation(TCM), Partial Response Fading Channel(PRFC)
Intelligent algorithms of construction of public transport routes

Today, in public transport planning systems, it is relevant to a search for a possible route with a minimum time. The aim of the work is the development of intelligent algorithms for constructing public transport routes, the development of programs, and the conduct of a computational experiment. Research methods are the theory of neural networks. The paper considers Hopfield neural networks and proposed recurrent neural networks. However, in Hopfield neural networks, the chances of solving this optimization problem decrease as the matrix size increases. A recurrent neural network is proposed, represented by a differential equation to solve this problem. As a result, the number of iterative computations can be reduced by n2 times than in the Hopfield network.
Affirmative Action and its Race-Neutral Alternatives

As afﬁrmative action loses political feasibility, many universities have implemented race-neutral alternatives like top percent policies and holistic review to increase enrollment among disadvantaged students. I study these policies’ application, admission, and enrollment effects using University of California administrative data. UC’s afﬁrmative action and top percent policies increased underrepresented minority (URM) enrollment by over 20 percent and less than 4 percent, respectively. Holistic review increases implementing campuses’ URM enrollment by about 7 percent. Top percent policies and holistic review have negligible effects on lower-income enrollment, while race-based afﬁrmative action modestly increased enrollment among very low-income students. These ﬁndings highlight that the most common race-neutral alternatives to afﬁrmative action increase Black and Hispanic enrollment far less than afﬁr-mative action itself and reveal that none of these policies substantially affect universities’ socioeconomic composition.

Examining the determinants of consumer support for corporate social advocacy

PurposeUsing the theory of planned behavior (TPB) as a theoretical framework, this study investigates individual level psychological determinants of individuals word-of-mouth (WOM) intentions as a way to support corporate social advocacy (CSA). Design/methodology/approachAn online survey (N = 505) using a Qualtrics panel was conducted.FindingsIndividuals' attitudes towards WOM, subjective norms, and self-efficacy was positively associated with their positive WOM intention, whereas perceived controllability over WOM behaviors was not associated with WOM intention. Age was negatively associated with WOM intention.Originality/valueThis study is one of the early attempts to test individual level factors in shaping individuals' WOM intention in response to CSA. This study also employed recent TPB argument and tested the role of self-efficacy and perceived controllability on behavioral intentions in the context of corporate communication. The findings of this study offer theoretical and practical insights to corporations when developing CSA campaigns and designing CSA messages.
Orthodontic Retainers—A Critical Review

The achievement of aesthetic, functional occlusion should not mark the end of the orthodontic intervention. To prevent relapse, retention needs advance planning, and may vary in duration. This review aims to present and comment on the available means of retention. The ever-popular, passive Hawley-like removable appliances are credible in maintaining the desired occlusion. Modifications are the removable appliance Wrap Around, having the labial archwire extending to the premolars; the translucent retainer, Astics, a unique aesthetic Hawley-type device; and the reinforced removable retainer, which features a metallic grid reinforcing the acrylic base. Vacuum-formed retainers are easy to fabricate and are readily prescribed. By contrast, fixed retainers are made of orthodontic wire and composite resin bonded on the lingual or palatal surfaces of the anterior teeth. Patient-related variables need evaluation to select the appropriate retainer, while patients ought to realize the importance of retention and comply with offered guidance. Overall, the orthodontist is responsible for keeping the patient informed on the properties and the duration of retention, even before starting active orthodontic treatment.
Unusual Suspects: Bone and Cartilage ECM Proteins as Carcinoma Facilitators

Simple Summary To provide insights into the role of the extracellular matrix (ECM) in health and pathological conditions, it is important to identify tissue-specific proteins, their interacting networks and functions. Latest discoveries suggest that multiple tumors express, and use to their advantage, atypical ECM components that are not found in the cancer tissue of origin. The aim of this review was to summarize and critically assess available information on the expression and function of atypical carcinoma-, bone- and cartilage-specific components of the extracellular matrix. To the best of our knowledge, this topic has not previously been covered by any published review, and thus provides a novel perspective for devising strategies to target tumor stroma as anti-cancer therapeutic options. Abstract The extracellular matrix (ECM) is the complex three-dimensional network of fibrous proteins and proteoglycans that constitutes an essential part of every tissue to provide support for normal tissue homeostasis. Tissue specificity of the ECM in its topology and structure supports unique biochemical and mechanical properties of each organ. Cancers, like normal tissues, require the ECM to maintain multiple processes governing tumor development, progression and spread. A large body of experimental and clinical evidence has now accumulated to demonstrate essential roles of numerous ECM components in all cancer types. Latest findings also suggest that multiple tumor types express, and use to their advantage, atypical ECM components that are not found in the cancer tissue of origin. However, the understanding of cancer-specific expression patterns of these ECM proteins and their exact roles in selected tumor types is still sketchy. In this review, we summarize the latest data on the aberrant expression of bone and cartilage ECM proteins in epithelial cancers and their specific functions in the pathogenesis of carcinomas and discuss future directions in exploring the utility of this selective group of ECM components as future drug targets.
The Euclidean root of Snell’s law I. Geometric polarization optics

Coset spaces of the Euclidean group of rigid motions in three‐space are used as a model of the rays in geometric polarization optics. The Haar measure invariance leads to canonicity of the phase space transformations. The phase space of optical rays undergoes a canonical map also under the effect of smooth refracting or reflecting surfaces between two optical media that is governed by Snell’s law. This is a conservation law between two irreducible representations of the Euclidean group labeled by the refractive indices n, n’ of the media. These surface transformations are canonical and, furthermore, factorize into two root transformations that are also canonical. This factorization applies equally to the transformation of the polarization vector. The root transformation permits the computation of an aberration expansion of the polarization field over the object screen. The generators of infinitesimal surface transformations are found, i.e., those that transform between media n and n+dn. It is shown that, .
Lifetime Matrix in Collision Theory

The duration of a collision is usually a rather ill-defined concept, depending on a more or less arbitrary choice of a collision distance. If the collision lifetime is defined as the limit, as $R\ensuremath{\rightarrow}\ensuremath{\infty}$, of the difference between the time the particles spend within a distance $R$ of each other and the time they would have spent there in the absence of the interaction, a well-defined quantity emerges which is finite as long as the interaction vanishes rapidly enough at large $R$.
Diversity of Bacterial Soft Rot-Causing Pectobacterium Species Affecting Cabbage in Serbia

The aim of this work was to identify and characterize the pectolytic bacteria responsible for the emergence of bacterial soft rot on two summer cabbage hybrids (Cheers F1 and Hippo F1) grown in the Futog locality (Bačka, Vojvodina), known for the five-century-long tradition of cabbage cultivation in Serbia. Symptoms manifesting as soft lesions on outer head leaves were observed during August 2021, while the inner tissues were macerated, featuring cream to black discoloration. As the affected tissue decomposed, it exuded a specific odor. Disease incidence ranged from 15% to 25%. A total of 67 isolates producing pits on crystal violet pectate (CVP) medium were characterized for their phenotypic and genotypic features. The pathogenicity was confirmed on cabbage heads. Findings yielded by the repetitive element palindromic-polymerase chain reaction (rep-PCR) technique confirmed interspecies diversity between cabbage isolates, as well as intraspecies genetic diversity within the P. carotovorum group of isolates. Based on multilocus sequence typing (MLST) using genes dnaX, mdh, icdA, and proA, five representative isolates were identified as Pectobacterium carotovorum (Cheers F1 and Hippo F1), while two were identified as Pectobacterium versatile (Hippo F1) and Pectobacterium odoriferum (Hippo F1), respectively, indicating the presence of diverse Pectobacterium species even in combined infection in the same field. Among the obtained isolates, P. carotovorum was the most prevalent species (62.69%), while P. versatile and P. odoriferum were less represented (contributing by 19.40% and 17.91%, respectively). Multilocus sequence analysis (MLSA) performed with concatenated sequences of four housekeeping genes (proA, dnaX, icdA, and mdh) and constructed a neighbor-joining phylogenetic tree enabled insight into the phylogenetic position of the Serbian cabbage Pectobacterium isolates. Bacterium P. odoriferum was found to be the most virulent species for cabbage, followed by P. versatile, while all three species had comparable virulence with respect to potato. The results obtained in this work provide a better understanding of the spreading routes and abundance of different Pectobacterium spp. in Serbia.
Primary Arterial Hypertension and Drug-Induced Hypertension in Philadelphia-Negative Classical Myeloproliferative Neoplasms: A Systematic Review

The impact of primary arterial hypertension (HTN) in myeloproliferative neoplasms (MPNs) remains unclear, with scant literature available, mostly focusing on cardiovascular risk factors as a singular entity or on organ-specific HTN. Furthermore, available studies reporting findings on drug-induced HTN in MPNs report varying and contradictory findings. In consideration of the above, this study set out to systematically review the available literature and shed light on the occurrence of HTN in MPNs, its association with thrombosis, as well as the drugs used in MPN management that could increase blood pressure. The literature search yielded 598 potentially relevant records of which 315 remained after the duplicates (n = 283) were removed. After we screened the titles and the abstracts of these publications, we removed irrelevant papers (n = 228) and evaluated the full texts of 87 papers. Furthermore, 13 records did not meet the inclusion criteria and were excluded from the systematic review. Finally, a total of 74 manuscripts were entered into the qualitative synthesis and included in the present systematic review. Our systematic review highlights that HTN is the most common comorbidity encountered in MPNs, with an impact on both the occurrence of thrombosis and survival. Moreover, drug-induced HTN remains a challenge in the management of MPNs. Further research should investigate the characteristics of patients with MPNs and HTN, as well as clarify the contribution of HTN to the development of thrombotic complications, survival and management in MPNs. In addition, the relationship between clonal hematopoiesis of indeterminate potential, HTN, cardiovascular disease and MPNs requires examination in upcoming assessments.
Comparative study of confocal and heterodyne microscopy for imaging through scattering media

We investigate limits of the confocal microscope when applied to imaging through scattering layers and compare its performance with that of a correlation (heterodyne) microscope. Confocal laser scanning microscopy is shown to make possible imaging through scattering media owing to the spatial filtering of the signal back-reflected from the sample. Its performance is limited by the noise of the detection system and/or insufficient rejection of scattered light, depending on the sample under investigation. Correlation microscopy with narrow or broad bandwidth light can extend these limits by selective, optical amplification of the image information.
Voyager photopolarimeter stellar occultation of Saturn's rings

On August 25, 1981, the Voyager 2 photopolarimeter system observed a stellar occultation by Saturn's rings. We present a brief description of this experiment along with details of the data reduction. The occultation results are given in tabular and graphical form at a resolution of 60 km. Histograms of the frequency of optical depth show dominantly unimodal distributions in each of the classical ring elements. The frequency distribution of the entire ring system shows three modes at τ ≈ 0.08, τ ≈ 0.5, and τ ≳ 2.50.
