Near-diffraction-limited coherent emission from large aperture antiguided vertical-cavity surface-emitting laser arrays

We demonstrate that in-phase mode operation with a near-diffraction-limited beam can be realized in large aperture (up to 100 elements) antiguided vertical-cavity surface-emitting laser (VCSEL) arrays. A selective etching process with two-step metalorganic chemical vapor deposition is used for fabrication of the antiguided VCSEL array structures. Modal discrimination is enhanced by intentionally choosing a GaAs cap thickness so as to introduce suitable loss to array interelement regions. Far field patterns indicate in-phase mode operation from both triangular and rectangular geometry antiguided VCSEL arrays, which is in good agreement with theory.
Commissioning of the LIGO detectors

The goal of the laser interferometer gravitational-wave observatory (LIGO) project is to detect and study gravitational waves from astrophysical sources. Currently, three interferometers with arm lengths of several kilometres and a design strain sensitivity of order 2 × 10−23 Hz−1/2 are being commissioned at two independent sites in Hanford (WA) and Livingston (LA). This paper describes the current work towards achieving LIGO's final sensitivity.
Conservativeness, Stability, and Abstraction

One of the main problems plaguing neo-logicism is the Bad Company challenge: the need for a well-motivated account of which abstraction principles provide legitimate definitions of mathematical concepts. In this article a solution to the Bad Company challenge is provided, based on the idea that definitions ought to be conservative. Although the standard formulation of conservativeness is not sufficient for acceptability, since there are conservative but pairwise incompatible abstraction principles, a stronger conservativeness condition is sufficient: that the class of acceptable abstraction principles be strictly logically symmetrically class conservative. The article concludes with an examination of which classes of abstraction principles meet this criteria. 1 Introduction 2 The Technical State of the Art 3 Abstraction and Conservativeness 4 Abstraction Stabilized 5 Characterizing SLSC-Conservativeness 6 Conclusion 1 Introduction 2 The Technical State of the Art 3 Abstraction and Conservativeness 4 Abstraction Stabilized 5 Characterizing SLSC-Conservativeness 6 Conclusion

Beyond Blah Blah Blah: Climate and Historical Justice in Peter Dimock’s Daybook from Sheep Meadow

ABSTRACT As our planetary house burns down, greenhouse gas emissions continue to rise – a demented state of affairs normalized partly by the ways we (don’t) talk about it. Ecocidal business as usual, that is, is normalized by discursive business as usual, the ways those in power talk about climate amounting, in Greta Thunberg’s acute analysis, to “30 years of blah, blah, blah. ” What would it mean to repudiate that discursive business as usual? I read Peter Dimock’s recent novel, Daybook from Sheep Meadow: The Notebooks of Tallis Martinson (2021), as an important exploration of that urgent, overwhelming question, an exploration, I suggest, with important implications for how the category of “climate fiction” is defined in the first place. Recognizing that the “untold violence of a failing empire’s exterminatory exploitation of Earth’s limited resources” has produced a present in which “language itself becomes a casualty” (149), the book stages both the necessarily dumbfounding result of refusing the language of empire and the necessarily strange and estranging work of trying nonetheless to “speak without compromise from the ground of that refusal. ” In this, it works to speak beyond blah blah blah.
Historical review of electron beam ion sources (invited)

Thirty years have passed since the modern concept of the production of highly charged ions in dense electron beams was first proposed, and less since the first electron beam ion source (EBIS) was built and tested. Milestones from the EBIS history, and future prospects are described in view of today’s needs in the production and use of highly charged ions. Various versions of EBIS, such as the classic EBIS, the electron beam ion trap—EBIT, the cross-over EBIS (T)-XEBIS/T and others were constructed, studied, and used in different laboratories. The ion-by-ion and “evaporative” cooling techniques are used to increase the time of ion confinement in an electron beam, ion charge states and ion yield. An alternative way to increase the ion yield is an increase of the electron beam current. The different concept of an ion source based on EBIS which uses multiple reflection of primary electrons and formation of a so-called electron string state is studied as well. Stability of electron-ion systems and nonexcitatio.
Analyzing CT images for detecting lung cancer by applying the computational intelligence‐based optimization techniques

Lung cancer is the most critical disease because it affects both men and women. Most of the time, lung cancer leads to death due to less health care and medical attention. In addition, lung cancer is difficult to identify in earlier stages due to the low‐level symptoms and risk factors. To overcome the complexity, effective techniques must predict lung cancer earlier. To attain the problem statement, an lung cancer identification system is developed with the help of a meta‐heuristic algorithm. The CT imageries obtained from the CIA database are analyzed step by step. The gathered image noise is removed by applying the mean filter, and the affected regions are segmented with the help of the Butterfly Optimization Algorithm‐based K‐Means Clustering (BOAKMC) algorithm. Afterward, various statistical features are derived, and the Supervised Jaya Optimized Rough Set related Feature Selection (SJORSFS) process is used to select the lung features. Finally, the lung cancer is identified using Autoencoder based Recurrent Neural Network (ARNN) classification algorithm, successfully recognizing the lung cancer features. Then the system's efficiency is evaluated using a MATLAB setup; here, 3000 are treated as training images and 2043 for testing images. The effective training enhances overall lung cancer prediction accuracy by up to 99.15%.
Investigations of 6LiIn1-xGaxSe2 semi-insulating crystals for neutron detection

Neutron detectors are used for illicit material detection, neutron radiography, stellar investigations of chemical content including biological compounds in planetary terrain and to monitor nuclear power plant fuel products and radioactive waste. Li-containing chalcogenide materials are promising alternative thermal neutron detection materials due to the incorporation of the 6Li isotope at high density. 6LiInSe2 is limited in its effective thermal neutron efficiency by 115In neutron capture which results in gamma decay rather than charge creation. This study includes investigations of mixed crystalline material 6LiIn1-xGaxSe2 where the indium concentration is reduced by Ga substitution. The optical properties have been tuned by gallium substitution and radiation response has been observed.
A physical model of the infrared-to-radio correlation in galaxies

We explore the implications of the IR-radio correlation in star-forming galaxies, using a simple physical model constrained by the constant global ratio q of IR to radio emission and by the radial falloff of this ratio in disks of galaxies. The modeling takes into account the diffusion, radiative decay, and escape of cosmic-ray electrons responsible for the synchrotron emission, and the full range of optical depths to dust-heating photons. We introduce two assumptions: that dust-heating photons and radio-emitting cosmic-ray electrons are created in constant proportion to each other as part of the star formation activity, and that gas and magnetic field are well coupled locally, expressed as B proportional to n exp beta, with beta between 1/3 and 2/3. We conclude that disk galaxies would maintain the observed constant ratio q under these assumptions if the disk scale height h(0) and the escape scale length l(esc) for cosmic-ray electrons followed a relation of the form l(esc) proportional to h(0) exp 1/2; the IR-to-radio ratio will then depend very weakly on interstellar density, and, therefore, on magnetic field strength or mean optical depth.

Total Synthesis and Bioactivity Evaluation of Hydrophobic Microcionamide‐Inspired Peptides

In this report, we describe the facile synthesis of four microcionamide‐inspired peptides where the atypical 2‐phenylethylenamine (2‐PEA) functional group in the marine natural product, microcionamide A, was replaced with a similarly‐aromatic but more easily incorporated tryptophan (Trp) residue. Compounds 1–4 were synthesized using a standard Fmoc‐based solid‐phase synthesis strategy followed by iodine‐mediated on‐resin cyclization for disulfide‐bridged compounds 1–3. Compound 1 showed antimicrobial activity against Staphylococcus aureus and Pseudomonas aeruginosa, with minimum inhibitory concentrations (MICs) of 9.1 μM and 15 μM, respectively. The inactivity of alanine analogs 2–4 against these pathogens suggests that the N‐terminal Val, the cyclic scaffold, the contiguous Ile residues, and consequently, the hydrophobicity of compound 1 are essential for antibacterial activity. Compound 1 also favorably exhibited minimal cytotoxicity against normal mammalian cell lines. In summary, we have synthesized an analog of microcionamide A where replacement of the 2‐PEA moiety with a Trp residue retained the antibacterial activity and with favorably low cytotoxicity.
Cardiac Dysfunction in People with Schizophrenia: Linking Clinical Outcome, the Heart, and the Brain

While cardiovascular disease remains the primary cause of mortality in people with schizophrenia, the link between cardiac dysfunction and clinical outcome remains poorly understood. The current study is an exploratory analysis, where a total of thirteen participants with schizophrenia were included to examine clinical outcome, cardiac structure and function, and brain volume of the anterior cingulate cortex (ACC) as measured by magnetic resonance imaging, where those participants achieving remission (N = 7) had better global functioning, with fewer positive and negative symptoms on PANSS and SNS. Cardiac function and structure did not differ between remitted and non-remitted groups; but, those not in remission had significantly less volume in the left ACC. As a whole sample, no significant relationships were found between ACC volume and clinical symptoms; however, inverse relationships between social withdrawal and left ventricular end diastolic volume (LVEDV), left ventricular end systolic volume (LVESV), left ventricle stroke volume (LVSV), left-ventricular concentricity (a ratio of left ventricular EDV/mass), and right ventricular end systolic volume (RVESV) were observed. Moreover, bilateral ACC volume was significantly correlated with higher LVEDV, LVSV, RVSV, and lower LV Concentricity, whereas only the left ACC was significantly related to higher RVEDV. Of note, all participants had significantly increased left ventricular concentricity compared to the general population. These results support that clinical outcome is indeed related to brain volume but may not be related to cardiac measures of function and structure in people with schizophrenia, but more research is required to verify these conclusions and to further explore the mechanisms of cardiac dysfunction.
Asymptotic behaviour of the mean integrated squared error of kernel density estimators for dependent observations

Let X1, X2, … be a strictly stationary sequence of observations, and g be the joint density of (X1, …, Xd) for some fixed d ⩽ 1. We consider kernel estimators of the density g. The asymptotic behaviour of the mean integrated squared error of the kernel estimators is obtained under an assumption of weak dependence between the observations. Soient X1X2, … des variables aleatoires formant une suite stationnaire au sens stricte et, pour d ≤ 1 donne, soit g la densite conjointe du vecteur (X1, …, Xd). Nous considerons les estimateurs par noyau pour la densite g. Sous une hypothese de faible dependance entre les observations, nous trouvons le comportement asymptotique de l'erreur quadratique moyenne integree de ces estimateurs.
Potential inhibitors of FemC to combat Staphylococcus aureus: virtual screening, molecular docking, dynamics simulation, and MM-PBSA analysis

Abstract FemC is a methicillin resistance factor involved in the alterations of peptidoglycan and glutamine synthesis in Staphylococcus aureus. To identify the potent antibacterial agents, antibacterial molecules were screened against the predicted and validated FemC model. Based on docking scores, presence of essential interactions with active site residues of FemC, pharmacokinetic, and ADMET properties, six candidates were shortlisted and subjected to molecular dynamics to evaluate the stability of FemC-ligand complexes. Further, per residue decomposition analysis and Molecular Mechanics/Poisson-Boltzmann Surface Area (MMPBSA) analysis confirmed that S15, M16, S17, R31, R43, Q47, K48 and R49 of FemC played a vital role in the formation of lower energy stable FemC-inhibitor(s) complexes. Therefore, in the present study, the reported six molecules (Z317461228, Z92241701, Z30923155, Z30202349, Z2609517102 and Z92470167) may pave the path to design the scaffold of novel potent antimicrobials against S. aureus.

Efficient encoding of speech LSP parameters using the discrete cosine transformation

The intraframe and interframe correlation properties are used to develop two efficient encoding algorithms for speech line spectrum pair (LSP) parameters. The first algorithm (2-D DCT), which requires relatively large coding delays, is based on two-dimensional (time and frequency) discrete cosine transform coding techniques; the second algorithm (DCT-DPCM), which does not need any coding delay, uses one-dimensional discrete cosine transform in the frequency domain and DPCM (differential pulse-code modulation) in the time domain. The performances of these systems for different bit rates and delays are studied, and appropriate comparisons are made. It is shown that an average spectral distortion of approximately 1 dB/sup 2/ can be achieved with 21 and 25 bits/frame using the 2-D DCT and DCT-DPCM schemes, respectively. This is a noticeable improvement over the previously reported bit rates of 32 bits/frame and above. <<ETX>>
Asymptomatic Intraosseous Meningioma of the Humerus: A Case Report and Review of the Literature

Meningiomas are the most common central nervous system tumor. They are typically benign neoplasms but may produce neurological symptoms due to mass effect. Meningiomas may also extend to extradural locations; however, these account for only a small percentage of all meningiomas. Most extradural meningiomas arise in intraosseous locations, usually within the cranial bones or vertebrae. However, this is a rare case of extradural extension of an asymptomatic intracranial meningioma to the proximal humerus in the absence of any musculoskeletal symptoms. To the best of our knowledge, this presentation of an extradural intraosseous meningioma has not previously been reported in the literature. We present a case of an incidental intraosseous meningioma in a 66-year-old man. This patient was initially being screened for metastasis of stage IA1 adenocarcinoma of the lung, and a positron emission tomography (PET) scan revealed a focus of activity in the proximal diaphysis of the right humerus suspicious for malignancy. The upper extremity magnetic resonance imaging (MRI) demonstrated an indeterminate lesion. Curettage of the humeral lesion revealed an intraosseous psammomatous meningioma without evidence of metastatic lung carcinoma. Our case report aims to illustrate the importance of considering alternative metastatic sources, such as intracranial meningioma, during the investigation of an indeterminate bony lesion. This is the first case to illustrate asymptomatic intraosseous meningioma in an appendicular skeletal location, highlighting the need for thorough source investigation.
An Analytic Solution to Projector Pose Estimation Problem

We present an analytic solution to the projector pose estimation problem for the pinhole projection model in which the source image is a centered rectangle with an unknown aspect ratio. From a single quadrilateral given as a target image, our solution gives the position and orientation of a projector as well as the aspect ratio of a source image. The proposed method decomposes the problem into two pose estimation problems of coupled line projectors aligned at each diagonal of the given quadrilateral and then computes the common solution that satisfies the relevant geometric constraints. The solution is formulated as simple analytic equations. We also provide a determinant of projectability of an arbitrary quadrilateral.
Optical environments of radio quasars

CCD images of 36 radio-loud quasars in the redshift range 0.1-0.75 are discussed. The objects were chosen to represent the full range of radio structure found with VLA A-configuration observations. Measured quantities are compared and correlated from both radio and optical observations. At least 70 percent of the quasars show evidence for current or recent interaction. Consideration is given to host galaxy sizes and luminosities, states of tidal interaction and numbers of companions, radio morphology, and luminosity.
Public Discourse Regarding Polrisesuaiprosedur Hashtag as a Trust Issue

This study attempted to describe on how political discourse develops through social media’s hashtags. #PolriSesuaiProsedur hashtag originally appeared to quell another viral hashtag, #PercumaLaporPolisi. This study used social network analysis between multiple internet accounts to shed light on how conversations on social media can actually develop into public discourse based on the hashtag #PolriSesuaiProsedur. This research became important since it would show the extent of public’s trust in the police institution. The research would be conducted on 3 phases. First, big data analysis to see the spread of netizens' conversations related to the #PolriSesuaiProsedur hashtag. Second, a quantitative survey on 5 regencies/cities in Banten Province. Third, FGD to strengthen a comprehensive outlook related to public discussions about trust in the police. The results of the data showed that the #PolriSesuaiProsedur hashtag described an issue that was not organic and centered only on one position. The results also showed how people responded to the hashtag and produced a bubble filter effect that encouraged the emergence of homogenous opinions and behaviors in the society.
Megalopinakophobia: its symptoms and cures

This paper addresses issues in the calculation of a detectability measure for the ideal linear (Hotelling) observer performing a detection task on a digital radiograph. The main computational problem is that the inverse of a very large covariance matrix is required. The conventional approach is to assume some form of stationarity and argue that the matrix is diagonalized by discrete Fourier transformation, but there are many reasons why this assumption is unrealistic. After a brief review of the underlying mathematics, we present several practical algorithms for computing the detectability and some hints as to when each is applicable. The main conclusion is that large matrices should not be feared.
Structural Diversities and Phylogenetic Signals in Plastomes of the Early-Divergent Angiosperms: A Case Study in Saxifragales

As representative of the early-divergent groups of angiosperms, Saxifragales is extremely divergent in morphology, comprising 15 families. Within this order, our previous case studies observed significant structural diversities among the plastomes of several lineages, suggesting a possible role in elucidating their deep phylogenetic relationships. Here, we collected 208 available plastomes from 11 constituent families to explore the evolutionary patterns among Saxifragales. With thorough comparisons, the losses of two genes and three introns were found in several groups. Notably, 432 indel events have been observed from the introns of all 17 plastomic intron-containing genes, which could well play an important role in family barcoding. Moreover, numerous heterogeneities and strong intrafamilial phylogenetic implications were revealed in pttRNA (plastomic tRNA) structures, and the unique structural patterns were also determined for five families. Most importantly, based on the well-supported phylogenetic trees, evident phylogenetic signals were detected in combinations with the identified pttRNAs features and intron indels, demonstrating abundant lineage-specific characteristics for Saxifragales. Collectively, the results reported here could not only provide a deeper understanding into the evolutionary patterns of Saxifragales, but also provide a case study for exploring the plastome evolution at a high taxonomic level of angiosperms.
