Published: November 2021

We report a robust method of stabilizing a laser to the frequency of an atomic transition using a hollow cathode lamp. In contrast to the standard dichroic atomic vapor laser lock method, which uses dichroism induced by a longitudinal magnetic field, we employ birefringence induced by a transversal magnetic field. We applied this method to the

Published: November 2021

The local wavefront modulation technique in the terahertz band is an important basis for the development of terahertz modulation technology. Here, an electrically controlled convergent tunable device based on patterned transparent electrode poly (3, 4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) is realized to locally tune the terahertz wavefront. The device consists of two substrates with circular-hole electrodes and liquid crystal sandwiched between them. The refractive index gradient of liquid crystal in the device can be generated by the coaxial double-hole electrodes, which realize continuous control of significant focusing of the terahertz wave. The test results show that the focal length can be modulated in the range of 3–12 cm with varied external voltage; when it varies from 3 to 8 V, the

radius of the spot decreases to 1.3 mm, 0.27 times the initial state, and the spot central intensity magnification increases gradually with the change, up to 3.31 times. The acquisition of the large tunable focal length range of the continuous terahertz zoom device shows that the construction of the gradient refractive index is an important method to regulate the terahertz wavefront by optical means, which greatly promotes the research of terahertz imaging devices.
Scheme for optimizing a direct current component in a photonics-assisted OFDM MMW system
Authors: Zhao Li , Sang Bohan , Zhou Wen , Wei Yi , Yu Jianjun 
Published: November 2021

This Letter proposes a new scheme for optimizing a direct current (DC) component to enable both the frequency offset estimation and system performance improvement by controlling the IQ modulator to adjust the DC component in a photonics-assisted OFDM MMW system. Compared with the traditional method, a large DC component is used as the pilot frequency for frequency offset estimation. When a small DC component is used, the system performance is better. A 3 Gbaud 16QAM OFDM signal is delivered over 70 m wireless, enabling a 3.5 dB sensitivity improvement at the bit error rate threshold of

A photonics-aided dual-functional system that can simultaneously implement high-speed communication and high-resolution radar detection is proposed. In the proposed system, high-speed orthogonal frequency division multiplexing signals and broadband linear frequency modulated signals are simultaneously realized based on photonic heterodyning. Based on this system, a net rate of 46.55 Gbit/s and radar with a 15 GHz bandwidth in the W-band were achieved.
Electrically controllable terahertz metamaterials with large tunabilities and low operating electric fields using electrowetting-on-dielectric cells
Authors: Silalahi Harry Miyosi , Shih Yi-Hong , Lin Shih-Hung , Chen Yi-Ting , Wei Wan-Yi , Chao Pei-Ling , Huang Chia-Yi 
Published: November 2021

A simple method that is compatible with all geometrical structures of terahertz (THz) metamaterials for increasing their frequency tunabilities and decreasing their operating electric fields is proposed. This method uses the displacement of glycerol droplets with various volumes to tune the resonance frequency of a THz metamaterial in an electrowetting-on-dielectric (EWOD) cell. The experimental results reveal that the THz metamaterial has a large frequency tunability of 28% at an operating electric field that is smaller than 0.2 V/µm as the glycerol droplets move in and out of the path of a THz beam. The frequency tunability is large because the near field of the metamaterial “experiences” a large difference between the refractive indices of glycerol and air. The EWOD cell with the THz metamaterial is a great achievement for developing electrically controllable band-stop filters with large frequency tunabilities and small operating electric fields.
‘All across Europe it had come’: The Black Death and Fascism in Sylvia Townsend Warner’s The Corner That Held Them
Authors: Piette Adam 
Published: November 2021

Sylvia Townsend Warner’s wartime novel The Corner that Held Them (1948), about a nunnery during the Black Death, reflects on female community and bonding in a period of male fascist violence. The novel explores the shift from pacifism to acceptance of the need for anti-fascist war which characterised Warner’s intellectual beliefs from the 1930s into wartime, probing the arts of peace in compositional practice. Such a dialectic of war and peace is considered in relation to what Maud Ellmann has described as the outward turn to collective choral consciousness in mid-century modernism. This article explores both the staging of fascism as plague and the feminist daring and limits that Warner saw as operative in female witnessing and withstanding of Nazi ideology and menace. It closely reads key scenes from the panorama of a novel (notably Alianor’s stillness as her husband is killed, Alicia’s plans to withstand the economic impact of the Black Death and the cure of Ralph’s plague symptoms) to register the satirical and allegorical substance of Warner’s rescripting of Woolfian notions of resistance to warmongering misogyny by a society of outsiders.
The readings seek to consolidate a varied and multiple sense of the book as a Marxist historical novel that gives voice to the ruled. In doing so Warner analyses the Black Death as a moment in history that saw the emergence of early modern capitalism and labour relations out of the feudal system, even as the religious framework that had structured medieval Europe gave way to more secular beliefs in autonomy, self-determination, citizen and collective dreams, projects and affects. At the same time the plague as a political trope, rooted in anti-fascist rhetoric that turns Nazi anti-Semitic uses of the Black Death motif on their head, triggers readings that bring those historical scenes into allegorical relation with the ways in which the Second World War was experienced by marginalised female communities.

Published: November 2021

Pencemaran udara adalah masuknya atau bercampurnya unsur-unsur berbahaya ke atmosfer yang dapat menyebabkan kerusakan lingkungan, gangguan kesehatan manusia pada umumnya, dan penurunan kualitas lingkungan. Salah satu solusi untuk mengatasi masalah pencemaran udara adalah dengan merencanakan Green Belt. Green Belt atau Sabuk hijau adalah kawasan bebas bangunan atau ruang terbuka hijau di sekitar kawasan sumber pencemar yang berguna sebagai penyaring fisik pencemar udara serta aspek lain seperti estetika, fungsi peneduh dan penunjang keanekaragaman hayati. Oleh karena itu, perencanaan Green Belt menjadi penting sebagai aspek yang dapat mengendalikan tingkat pencemaran udara, khususnya pencemaran debu, pada lokasi perencanaan yang ditargetkan, khususnya Kawasan Industri Terboyo. Berdasarkan sampling yang dilakukan, angka konsentrasi debu menunjukkan angka yang cukup tinggi yaitu 801,6 mg/m3. Dengan desain Green Belt jenis pohon Acacia mampu menurunkan konsentrasi debu mulai dari efisiensi 15,84% pada tahun tanam dan meningkat pesat setiap tahunnya. Efisiensi optimal Green Belt akan tercapai pada tahun ke-2 dengan laju 71,40% dan akan mampu mencapai efisiensi maksimum pada tahun ke-5 dengan laju 87,92%. ABSTRACTAir pollution is the entry or mixing of hazardous elements into the atmosphere which can cause environmental damage, disturbances to human health in general and reduce environmental quality. One of the solutions to tackle air pollution problems is to plan a Green Belt. Green belt is a building-free zone or green open space around the pollutant source area which is useful as a physical filter for air pollutants as well as other aspects such as aesthetics, shading functions, and biodiversity support. Therefore, planning a Green Belt is important as an aspect that can control the level of air pollution, especially dust pollution, at the targeted planning location, especially Terboyo Industrial Area. Based on the sampling carried out, the dust concentration figure shows a high number, namely 801.6 mg / m3. With the Acacia tree species Green Belt design, it can reduce dust concentrations starting from an efficiency of 15.84% in the planting year and increasing rapidly each year. The optimum efficiency of the Green Belt will be achieved in the 2nd year with the rate of 71.40% and it will be able to reach the maximum efficiency in the 5th year with the rate of 87.92%.

Mapping the Microstructure and Striae of the Human Olfactory Tract with Diffusion MRI
Authors: Echevarria-Cooper Shiloh L. , Zhou Guangyu , Zelano Christina , Pestilli Franco , Parrish Todd B. , Kahnt Thorsten 
Published: November 2021

The human sense of smell plays an important role in appetite and food intake, detecting environmental threats, social interactions, and memory processing. However, little is known about the neural circuity supporting its function. The olfactory tracts project from the olfactory bulb along the base of the frontal cortex, branching into several striae to meet diverse cortical regions. Historically, using diffusion magnetic resonance imaging (dMRI) to reconstruct the human olfactory tracts has been prevented by susceptibility and motion artifacts. Here, we used a dMRI method with readout segmentation of long variable echo-trains (RESOLVE) to minimize image distortions and characterize the human olfactory tractsin vivo. We collected high-resolution dMRI data from 25 healthy human participants (12 male and 13 female) and performed probabilistic tractography using constrained spherical deconvolution (CSD). At the individual subject level, we identified the lateral, medial, and intermediate striae with their respective cortical connections to the piriform cortex and amygdala (AMY), olfactory tubercle (OT), and anterior olfactory nucleus (AON). We combined individual results across subjects to create a normalized, probabilistic atlas of the olfactory tracts. We then investigated the relationship between olfactory perceptual scores and measures of white matter integrity, including mean diffusivity (MD). Importantly, we found that olfactory tract MD negatively correlated with odor discrimination performance. In summary, our results provide a detailed characterization of the connectivity of the human olfactory tracts and demonstrate an association between their structural integrity and olfactory perceptual function.SIGNIFICANCE STATEMENTThis study provides the first detailedin vivodescription of the cortical connectivity of the three olfactory tract striae in the human brain, using diffusion magnetic resonance imaging (dMRI). Additionally, we show that tract microstructure correlates with performance on an odor discrimination task, suggesting a link between the structural integrity of the olfactory tracts and odor perception. Lastly, we generated a normalized probabilistic atlas of the olfactory tracts that may be used in future research to study its integrity in health and disease.

The chalcogenides LaxTbyErzPbSi2S8 were obtained by synthesizing the elementary components in vacuum quartz containers at 1320 K. The synthesized alloys were homogenized by annealing at 770 K during 500 hours. The cell parameters of synthesized sulfides are: a = 0,89576(3) nm, c = 2,65646(8) nm – La1,2Tb0,4Er0,4PbSi2S8; a = 0,89209(1) nm, c = 2,63466(5) nm – La0,9Tb0,2Er0,9PbSi2S8; a = 0,89002(3) nm, c = 2,62714(7) nm – La0,67Tb0,67Er0,67PbSi2S8; a = 0,88993(1) nm, c = 2,62973(4) nm – La0,6Tb1,2Er0,2PbSi2S8; a = 0,885161(7) nm, c = 2,60445(3) nm – La0,2Tb0,9Er0,9PbSi2S8 respectively. The atoms of statistical mixture (La,Tb,Er,Pb) occupy the site 18e (x y 1/4), and the atoms of Si occupy the site 12c (1/3 2/3 z) in the structure of the obtained chalcogenides. Coordinating polyhedra of atoms of the statistical mixture (La, Tb, Er, Pb) are trigonal prism with two additional atoms (CN = 8), and the atoms of Si occupying the crystallographic point system 12c describes with the tetrahedron. According to the results of the experiment, the synthesized chalcogenides crystallize in the structure type of La2PbSi2S8 (hR26,167). The structure of La2PbSi2S8 is described by using the theory of second anion coordination (SAC).
Luther’s Participative Ontology
Authors: Kampen Dieter 
Published: November 2021

Distinguishing between a relational and participative ontology and highlighting the last like a paradigm of our time, the author shows how Luther uses both types of ontology for the explication of justification and how both express the same concept in different ways. The participative paradigm explains justification through the union between Christ and the believer and the following communicatio idiomatum. The author underlines that this is not a personal union, but that Christ and the believer become one body and that this union doesn’t change human nature but giving a person a new direction. The article closes with some ecumenical considerations of the participative ­ontology.
Christ’s Real Presence in the Eucharist and Relational Ontology
Authors: Vainio Olli-Pekka 
Published: November 2021

This paper argues for an interpretation of the real of presence of Christ in the Eucharist using relational ontology as the basic metaphysical theory. Relational ontology, in its one form, denies the existence of intrinsic properties so that things that exists are just instantiations of particular sets of properties that receive their essence from their relation to other things. If there are good reasons to accept relational ontology, it could potentially help one to solve certain problems in transubstantiation model, without giving up the idea of real presence.

SOCIAL ASSISTANT WORK MANAGEMENT IN EDUCATION POLICY
Authors: Quadrado Jaqueline Carvalho , Lima Eduardo 
Published: November 2021

The study aimed to understand the importance of the Social Worker work management process in Education Policy, more specifically in the Coordination of Social Work Course. It was questioned whether the theoretical and methodological principles of management apply in the federal public sector, where the work to be carried out already obeys a previously planned and orchestrated agenda by the federal sphere, as it obeys plans and goals established by the managing bodies of policies public. Then, it was asked whether it would be possible to build the theoretical-practical process of management and how to carry it out in the field of professional practice, where the overvaluation of bureaucratic work directly interferes with professional action, a process that contributes to the construction of a practice emptied and uncritical professional. Also in this questioning guideline, it was also asked, what are the theoretical and practical principles of management that the social worker could appropriate as a work tool in his performance in the public sector, where the professional routinely runs into institutional limits and power relations established in the state apparatus. The documentary and bibliographic study was characterized by its exploratory character and qualitative approach. It was considered that the process of valuing bureaucratic work has been gradually encouraging the bureaucratization of practice and the professional void, a fact that conditions professional practice to bureaucratic and routine tasks. Work management and the ability to plan and organize professional action on a purposeful basis become instruments of great importance in the formulation of proposals to face the challenges posed to Social Service professionals.
