An iterative scheme based on deep learning combined with input noise estimator for phase data processing in digital holographic interferometry
Authors: Montresor Silvio , Tahon Marie , Laurent Antoine , Picart Pascal
Published: September 2020

This paper presents a deep-learning-based algorithm dedicated to the processing of the speckle noise in phase measurements in digital holographic interferometry. In order to train the network to de-noise phase fringe patterns, a database is constituted with a set of noise-free and noisy phase data corresponding to realistic decorrelation phase noise conditions. An iterative scheme coupled with an input noise level estimator allows improving the deep learning based approach especially for strong noise. Performance of the trained network is estimated and shows that this approach is close to the state-of-the-art of speckle de-noising in digital holographic phase measurements.

Fast Foveation for LIDARs, Projectors and Cameras
Authors: Koppal Sanjeev J.
Published: September 2020

Most cameras today capture images without considering scene content. In contrast, animal eyes have fast mechanical movements that control how the scene is imaged in detail by the fovea, where visual acuity is highest. This concentrates computational (i.e. neuronal) resources in places where they are most needed. The prevalence of foveation, and the wide variety of it, makes it very clear that this is an effective visual design strategy. If robotic drones had this kind of low power vision, we could imagine massive impact on a variety of fields. Allowing these small devices to reliably sense their surroundings has the potential for a major transformation in computer vision. In this talk, I cover our recent work on creating cameras and algorithms that enable fast, selective imaging. The key challenge is that these algorithms require novel camera designs with fast and low-power control of the physical properties that influence image formation. I will discuss examples of such cameras, LIDARs and projectors that utilize newly available, next generation micro-mechanical optics.
Toward lower-diameter large-scale HPC and data center networks with co-packaged optics
Authors: Maniotis Pavlos , Schares Laurent , Lee Benjamin G. , Taubenblatt Marc A. , Kuchta Daniel M.
Published: September 2020

We investigate the advantages of using co-packaged optics for building low-diameter, large-scale high-performance computing (HPC) and data center networks. The increased escape bandwidth offered by co-packaged optics can enable high-radix switch implementations of more than 150 switch ports, which can be combined with data rates of up to 400 Gb/s per port. From the network architecture perspective, the key benefits of using co-packaged optics in future fat-tree networks include (a) the ability to implement large-scale topologies of

. From the network operation perspective, both reduced energy consumption and lower packet delays can be achieved since fewer hops are required; i.e., packets need to traverse fewer serializer/deserializer lanes and fewer switch buffers, which reduces the probability of contending with other packets and improves the tolerance of network congestion. The performance of the proposed architecture is evaluated via discrete-event simulations for a wide range of representative HPC synthetic-traffic cases that include both hotspot and non-hotspot scenarios. The simulation results suggest that co-packaged optics form a promising solution to keep up with bandwidth scaling in future networks, while the reduced number of switching layers can lead to significant mean packet delay improvements that start from 30% and reach up to 74% for high-load conditions.

Authors: Nishizawa Hideki , Ishida Wataru , Sone Yoshiaki , Tanaka Takafumi , Kuwabara Seiki , Inui Tetsuro , Sasai Takeo , Tomizawa Masahito
Published: September 2020

In this paper, we identify challenges in developing future optical network infrastructure for new services based on technologies such as 5G, virtual reality, and artificial intelligence, and we suggest approaches to handling these challenges that include a business model, architecture, and diversity. Through activities in multiservice agreement and de facto standard organizations, we have shown how the hardware abstraction layer interfaces of optical transceivers are implemented for multivendor and heterogeneous environments, coherent digital signal processor interoperability, and optical transport whiteboxes. We have driven the effort to define the transponder abstraction interface with partners. The feasibility of such implementation was verified through demonstrations and trials. In addition, we are constructing an open-transport platform by combining existing open-source software and implementing software components that automate and enhance operations. An open architecture maintains a healthy ecosystem for industry and allows for a flexible, operator-driven network.
Three-dimensional imaging from single-element holographic data
Authors: Moscoso M. , Novikov A. , Papanicolaou G. , Tsogka C.
Published: September 2020

We present a holographic imaging approach for the case in which a
single source-detector pair is used to scan a sample. The
source-detector pair collects intensity-only data at different
frequencies and positions. By using an appropriate illumination
strategy, we recover field cross correlations over different
frequencies for each scan location. The problem is that these field
cross correlations are asynchronized, so they have to be aligned first
in order to image coherently. This is the main result of the paper: a
simple algorithm to synchronize field cross correlations at different
locations. Thus, one can recover full field data up to a global phase
that is common to all scan locations. The recovered data are, then,
coherent over space and frequency so they can be used to form
high-resolution three-dimensional images. Imaging with intensity-only
data is therefore as good as coherent imaging with full data. In
addition, we use an

ℓ

-norm minimization algorithm that
promotes the low dimensional structure of the images, allowing for
deep high-resolution imaging.
Degree of paraxiality of an anisotropic hollow multi-Gaussian Schell-model beam
Authors: Huang Ju , Wang Ziyuan , Ji Xiaoling , Wang Tao
Published: September 2020

Degree of paraxiality (DOP) of an anisotropic hollow multi-Gaussian Schell-model (HMGSM) beam is discussed, and the influence of parameters of the beam source on its DOP is studied. It is shown that the parameters of the beam source, including the anisotropy, boundary characteristic, beam waist width, and beam coherence width, may play an important role in its DOP. Moreover, in order to illustrate the behaviors of DOP, the far-field divergence angle of this beam source has also been investigated.
Diagnosing phase correlations in the joint spectrum of parametric downconversion using multi-photon emission
Authors: Bell Bryn A. , Triginer Garces Gil , Walmsley Ian A.
Published: September 2020

The development of new quantum light sources requires robust and convenient methods of characterizing their joint spectral properties. Measuring the joint spectral intensity between a photon pair ignores any correlations in spectral phase which may be responsible for degrading the quality of quantum interference. A fully phase-sensitive characterization tends to require significantly more experimental complexity. Here, we investigate the sensitivity of the frequency-resolved double-pair emission to spectral phase correlations, in particular to the presence of a simple form of correlated phase which can be generated by a chirped pump laser pulse. We observe interference fringes in the four photon coincidences which depend on the frequencies of all four photons, with a period which depends on the strength of their correlation. We also show that phase correlations in the JSA induce spectral intensity correlations between two signal photons, even when the corresponding idler photons are not detected, and link this correlation pattern to the purity of a single signal photon. These effects will be useful in assessing new photon-pair sources for quantum technologies, especially since we require little additional complexity compared to a joint spectral intensity measurement - essentially just the ability to detect at least two photons in each output port.

Published: September 2020

By developing a ‘two-crystal’ method for color erasure, we can broaden the scope of chromatic interferometry to include optical photons whose frequency difference falls outside of the 400 nm to 4500 nm wavelength range, which is the passband of a PPLN crystal. We demonstrate this possibility experimentally, by observing interference patterns between sources at 1064.4 nm and 1063.6 nm, corresponding to a frequency difference of about 200 GHz.
Entanglement enhanced by Kerr nonlinearity in a cavity-optomagnonics system
Authors: Yang Zhi-Bo , Liu Jin-Song , Jin Hua , Zhu Qing-Hao , Zhu Ai-Dong , Liu Hong-Yu , Ming Ying , Yang Rong-Can
Published: September 2020

We present a method to enhance steady-state bipartite and tripartite entanglement in a cavity-optomagnonics system by utilizing the Kerr nonlinearity originating from the magnetocrystalline anisotropy. The system comprises two microwave cavities and a magnon and represents the collective motion of several spins in a macroscopic ferrimagnet. We prove that Kerr nonlinearity is reliable for the enhancement of entanglement and produces a small frequency shift in the optimal detuning. Our system is more robust against the environment-induced decoherence than traditional optomechanical systems. Finally, we briefly analyze the validity of the system and demonstrate its feasibility for detecting the generated entanglement.
Influence of pump beam shaping and noise on performance of a direct diode-pumped ultrafast Ti:sapphire laser
Authors: Tahir jamal Muhammad , Hansen Anders Kragh , Tawfieq Mahmoud , Andersen Peter Eskil , Jensen Ole Bjarlin
Published: September 2020

One of the major factors that limits the widespread use of ultrafast titanium sapphire (Ti:S) lasers in life science is its expensive and complex pump source. Broad area diode laser (BA-DL) based pump sources have high potential to solve this problem, since they are compact, inexpensive and very efficient. However, their non-diffraction limited beam profile makes it challenging to achieve high powers in Kerr-lens mode-locked (KLM) operation of Ti:S lasers. In this work, we show that the ideal way to beam shape two spectrally combined BA-DLs with different beam qualities is to aim for a compromise between matching to the cavity mode diameter and the cavity mode Rayleigh range. We furthermore conclude that the relative intensity noise (RIN) of the BA-DL pumped Ti:S laser, another important parameter for imaging applications, is sufficiently low for a wide range of life science applications. However, for applications that are highly sensitive to noise, new laser diode designs are likely necessary to reduce inherent noise originating within the laser diode.

Características Técnicas do Cadastro Territorial Temático de Sítios Arqueológicos Brasileiros
Authors: Linheira Guilherme , Oliveira Francisco Henrique de
Published: September 2020

Os cadastros territoriais consistem em inventários públicos de dados diretamente relacionados à representação gráfica das parcelas e dos objetos territoriais. De modo complementar à geração do banco de dados do cadastro há a necessidade da caracterização jurídica da feição territorial representada (parcela ou objeto territorial). O objeto territorial é definido como uma porção de terra com condições homogêneas em seus limites, em função de sua finalidade. Portanto, todo elemento natural, artificial ou restritivo por legislação sobre o solo – tais como cursos d’água, áreas de conservação ambiental, e ainda os sítios arqueológicos potencialmente se enquadram como objeto territorial. A identificação e mapeamento destes elementos requisitam um conhecimento específico, mobilizando a participação de instituições especializadas, configurando os chamados cadastros territoriais temáticos. Sendo assim, o presente artigo apresenta como foco de estudo o Cadastro Nacional de Sítios Arqueológicos – CNSA. O CNSA é o sistema cadastral que contém as informações espaciais dos sítios arqueológicos localizados no território brasileiro, apresentando atualmente cerca de 27 mil registros, sendo gerenciado pelo Instituto do Patrimônio Histórico e Artístico Nacional - IPHAN. Neste contexto, o artigo caracteriza e analisa as características técnicas do cadastro temático vinculado aos sítios arqueológicos. Como resultado, destaca-se que o CNSA apresenta fragilidades com relação ao rigor no processo de medição geométrica de seus limites ao não estabelecer critérios mínimos e padronização técnica no referido processo. Dessa forma, gera incertezas e consequentemente inseguranças jurídicas no posterior uso destes dados.

Abstract Tax disputes can occur between taxpayers or tax insurers with the government, among others because of differences in the amount of tax payable. One of the legal efforts that can be taken by taxpayers in the event of a tax dispute is an "Objection" legal effort. This objection is essentially a legal effort that is outside the Tax Court to appeal for justice in a tax dispute. The problem, what weaknesses are there in the objection institutions that exist today. Some of the weaknesses in this tax objection institution include the position within the Directorate General of Taxes or precisely a unit/part that is part of the Tax Service Office (KPP) or the Tax Office. Its position under the Directorate General of Taxation is what has caused criticism from many parties, especially with regard to independence in deciding a case, the Independent is doubtful, there is a conflict of interest. Another disadvantage is the provision that contains a "threat" to taxpayers in filing objections, namely a fine of 50% of the amount of tax payable after deducting the amount of tax paid if the decision rejects the objection filed by the taxpayer or partially grants. Keywords: Objection, tax dispute, the taxpayer  Abstrak Sengketa pajak dapat terjadi antara wajib pajak atau penanggung pajak dengan pemerintah , antara lain karena perbedaan penghitungan besarnya pajak yang terutang.

Asas-Asas Umum Pemerintahan yang Baik dalam Pelayanan Publik
Authors: Solechan Solechan
Published: September 2020

Abstract AAUPB (Asas asas umum pemerintahan yang Baik)  has a long journey from the beginning of its birth in the Netherlands to its application in Indonesia today. AAUPB at first was only in the theoretical realm and then entered into law until AAUPB got a very important position in Law No. 30 of 2014. Initially, AAUPB was intended as a means of legal protection or rechtsbescherming and was even used as an instrument to increase legal protection or rechtsbescherming for citizens from government actions. AAUPB is then used as the basis for judgments in the judiciary and administrative efforts, as well as an unwritten legal norm for government actions  The history of the development of AUPB in Indonesia can be seen from the development of the AUPB principle in various laws and regulations, the practice of implementing the AUPB in court decisions or jurisprudence and doctrine. The development of the AUPB principle arrangement had found an increasingly strong momentum when the Government Administration Act was passed in 2014. As a result of the adoption of the concept of the welfare state, the state must fulfill the welfare of the community, one of which is through public services. With the AAUPB, it is expected that the government as a public service provider, can accept the AAUPB as a legal norm that must be used as the basis by the civil service provider in carrying out its authority, as well as a means for citizens to sue deviant public service providers. Keywords: General principles of good governance, public service. Abstrak Asas-asas umum pemerintahan yang baik (selanjutnya disebut AAUPB) lahir dari praktik penyelenggaraan negara dan pemerintahan sehingga bukan produk formal suatu lembaga negara seperti undang-undang. Asas-asas umum pemerintahan yang baik dapat dipahami sebagai asas-asas umum yang dijadikan sebagai dasar dan tata cara dalam penyelenggaraan pemerintahan yang layak, yang dengan cara demikian penyelenggaraan pemerintahan itu menjadi baik, sopan, adil, dan terhormat, bebas dari kezaliman, pelanggaran peraturan, tindakan penyalahgunaan wewenang dan tindakan sewenang-wenang. Sejarah perkembangan AUPB di Indonesia dapat dilihat dari perkembangan prinsip AUPB dalam berbagai peraturan perundang-undangan, praktik penerapan AUPB dalam putusan pengadilan atau yurisprudensi serta doktrin. Perkembangan pengaturan prinsip AUPB menemukan momentumnya yang semakin kuat, tatkala UU Administrasi Pemerintahan disahkan pada tahun 2014. Sebagai akibat dari dianutnya konsepsi welfare state maka negara memiliki kewajiban untuk memenuhi kesejahteraan masyarakat salah satunya melalui pelayanan publik. Dengan adanya AAUPB diharapkan pemerintah sebagai pemberi pelayanan publik dapat menerima AAUPB sebagai norma hukum yang harus dijadikan dasar oleh penyelenggara pelayanan publik dalam menjalankan kewenangannya, sekaligus sarana bagi warga negara untuk menggugat penyelenggara pelayanan publik yang menyimpang. Kata Kunci : Asas-asas umum pemerintahan yang baik, Pelayanan Publik

Authors: Shi Miao , Wang Chao , Li Xian-Zhe , Li Ming-Qiang , Wang Lu , Xie Neng-Gang
Published: September 2020

Electroencephalography (EEG) is a complex bioelectrical signal. Analysis of which can provide researchers with useful physiological information. In order to recognize and classify EEG signals, a pattern recognition method for optimizing the support vector machine (SVM) by using improved squirrel search algorithm (ISSA) is proposed. The EEG signal is preprocessed, with its time domain features being extracted and directed to the SVM as feature vectors for classification and identification. In this paper, the method of good point set is used to initialize the population position, chaos and reverse learning mechanism are introduced into the algorithm. The performance test of the improved squirrel algorithm (ISSA) is carried out by using the benchmark function. As can be seen from the statistical analysis of the results, the exploration ability and convergence speed of the algorithm are improved. This is then used to optimize SVM parameters. ISSA-SVM model is established and built for classification of EEG signals, compared with other common SVM parameter optimization models. For data sets, the average classification accuracy of this method is 85.9%. This result is an improvement of 2–5% over the comparison method.

Authors: Liu Yuankun , Wang Jianlong , Zhou Zhiwei , Zheng Xiaoying , Zhao Liyuan , Yu Aixin
Published: September 2020

This study evaluated gamma radiation-enhanced sulfamethazine (SMT) degradation, which belongs to the heterocyclic sulfonamides, in different conditions in aqueous solution. The results showed that gamma irradiation could increase the SMT removal in aqueous solution, and the SMT degradation kinetic follow the modified pseudo-first-order kinetic. The degradation rate was nearly 95% at the absorbed dose of 4 kGy. The removal of total organic carbon (TOC) and total nitrogen (TN) could be also induced. When the radiation dose was 5 kGy, the removal rates were only about 6.8% and 10.5% for TOC and TN, respectively. Some ions including HCOO−, CH3COO− and SO42− released during SMT degradation were studied. The biodegradability and toxicity of intermediate products of the SMT degradation were also proposed in this experiment. The biodegradability of the SMT can be improved by the intermediate products of SMT degradation at the radiation dose of 1, 2 and 5 kGy. Gamma radiation could be used as a pretreatment technology before the biodegradation process of pharmaceutical waste water.
Structure and some physicochemical and functional properties of water treated under ammonia with low-temperature low-pressure glow plasma of low frequency

Published: September 2020

Deionized, tap and two kinds of commercially available mineralized water, after supplementation with ammonia, were treated with low-pressure, low-temperature glow plasma (GP) of low frequency. Treating hard water with ammonia provided the removal of permanent and temporary water hardness already at room temperature. On such treatment, mineralized water supplemented with ammonia was partly demineralized. Precipitated rhombohedral deposit from hard water did not turn into scale even when maintained in suspension for 3 days at around 90°C. In such manner, the use of other chemicals for prevention from the scale formation and/or for the scale removal is entirely dispensable. The rate and yield of precipitation depended on the concentration of admixed ammonia and the GP treatment time. Ammonia served as a ligand of calcium, magnesium and ferric central atoms of corresponding salts constituting the hardness. Moreover, ammonia constituting the atmosphere of the treatment was arrested inside aqueous clathrates. So, stabilized ammonia solutions could potentially be utilized as an environmental-friendly nitrogen fertilizer. The precipitate could also be utilized for the same purpose.

Oxidative stress is a causative factor in the pathophysiology of numerous diseases, such as diabetes, atherosclerosis, cancer, and neurodegenerative and cardiovascular diseases. Therapeutic antioxidants are promising candidates for preventing and treating conditions in which oxidative stress is a contributing factor. In this study, we report the design, synthesis and antioxidant activity of six compounds containing the 2-methoxyphenol moiety core structure. The synthesized derivatives were characterized using 1H NMR, 13C NMR, Fourier-transform infrared (FT-IR), and elemental analysis spectroscopy. The antioxidant properties of the compounds were evaluated using the 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH), 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), and oxygen radical absorbance capacity (ORAC) assay. New phenolic acid-derived compounds with antioxidant activity were identified.

Deoxyribozymes (DNAzymes) are single-stranded DNA molecules that catalyze a broad range of chemical reactions. The 10–23 DNAzyme catalyzes the cleavage of RNA strands and can be designed to cleave essentially any target RNA, which makes it particularly interesting for therapeutic and biosensing applications. The activity of this DNAzyme in vitro is considerably higher than in cells, which was suggested to be a result of the low intracellular concentration of bioavailable divalent cations. While the interaction of the 10–23 DNAzyme with divalent metal ions was studied extensively, the influence of monovalent metal ions on its activity remains poorly understood. Here, we characterize the influence of monovalent and divalent cations on the 10–23 DNAzyme utilizing functional and biophysical techniques. Our results show that Na+ and K+ affect the binding of divalent metal ions to the DNAzyme:RNA complex and considerably modulate the reaction rates of RNA cleavage. We observe an opposite effect of high levels of Na+ and K+ concentrations on Mg2+- and Mn2+-induced reactions, revealing a different interplay of these metals in catalysis. Based on these findings, we propose a model for the interaction of metal ions with the DNAzyme:RNA complex.
When is it OK to Joke? Adding humor to fear-based colonoscopy screening messages may increase compliance
Authors: Carcioppolo Nick , Occa Aurora , Chudnovskaya Elena V.
Published: September 2020

Large scale campaigns frequently use humor to increase compliance with colonoscopy screening recommendations. Problematically, we know little about how humor functions to influence screening. This study seeks to understand whether and how messages framed using humor appeals function differently from those using fear appeals to increase colonoscopy intentions. An online experiment (N = 186) was conducted comparing colonoscopy screening messages framed with a fear appeal and mixed humor/fear appeal. The addition of humor was more effective among those with high frequency of cancer worry, whereas the fear appeal resulted in significantly higher response efficacy, which was in turn associated with increased colonoscopy intentions. These results begin to describe situations in which intervention messages framed with a mixed humor/fear appeal may be more or less effective than interventions framed with fear appeals alone. Practical and theoretical implications for persuasive message design are discussed.
Monadic pseudo BE-algebras
Authors: Ciungu Lavinia Corina
Published: September 2020

In this paper we define the monadic pseudo BE-algebras and investigate their properties. We prove that the existential and universal quantifiers of a monadic pseudo BE-algebra form a residuated pair. Special properties are studied for the particular case of monadic bounded commutative pseudo BE-algebras. Monadic classes of pseudo BE-algebras are investigated and it is proved that the quantifiers on bounded commutative pseudo BE-algebras are also quantifiers on the corresponding pseudo MV-algebras. The monadic deductive systems and monadic congruences of monadic pseudo BE-algebras are defined and their properties are studied. It is proved that, in the case of a monadic distributive commutative pseudo BE-algebra there is a one-to-one correspondence between monadic congruences and monadic deductive systems, and the monadic quotient pseudo BE-algebra algebra is also defined.

Integration with respect to deficient topological measures on locally compact spaces
Authors: Butler Svetlana V.
Published: September 2020

Topological measures and deficient topological measures generalize Borel measures and correspond to certain non-linear functionals. We study integration with respect to deficient topological measures on locally compact spaces. Such an integration over sets yields a new deficient topological measure if we integrate a nonnegative continuous vanishing at infinity function; and it produces a signed deficient topological measure if we integrate a continuous function on a compact space. We present many properties of these resulting deficient topological measures and of signed deficient topological measures. In particular, they are absolutely continuous with respect to the original deficient topological measure, and their corresponding non-linear functionals are Lipschitz continuous. Deficient topological measures obtained by integration over sets can also be obtained from non-linear functionals. We show that for a deficient topological measure μ that assumes finitely many values, there is a function f such that

Cell Assemblies in the Cortico-Hippocampal-Reuniens Network during Slow Oscillations

Published: September 2020

The nucleus reuniens (NR) is an important anatomic and functional relay between the medial prefrontal cortex (mPFC) and the hippocampus (HPC). Whether the NR controls neuronal assemblies, a hallmark of information exchange between the HPC and mPFC for memory transfer/consolidation, is not known. Using simultaneous local field potential and unit recordings in NR, HPC, and mPFC in male rats during slow oscillations under anesthesia, we identified a reliable sequential activation of NR neurons at the beginning of UP states, which preceded mPFC ones. NR sequences were spatially organized, from dorsal to ventral NR. Chemical inactivation of the NR disrupted mPFC sequences at the onset of UP states as well as HPC sequences present during sharp-wave ripples. We conclude that the NR contributes to the coordination and stabilization of mPFC and HPC neuronal sequences during slow oscillations, possibly via the early activation of its own sequences.

SIGNIFICANCE STATEMENTNeuronal assemblies are believed to be instrumental to code/encode/store information. They can be recorded in different brain regions, suggesting that widely distributed networks of networks are involved in such information processing. The medial prefrontal cortex, the hippocampus, and the thalamic nucleus reuniens constitute a typical example of a complex network involved in memory consolidation. In this study, we show that spatially organized cells assemblies are recruited in the nucleus reuniens at the UP state onset during slow oscillations. Nucleus reuniens activity appears to be necessary to the stability of medial prefrontal cortex and hippocampal cell assembly formation during slow oscillations. This result further highlights the role of the nucleus reuniens as a functional hub for exchanging and processing memories.
