Joint Beamforming and Aerial IRS Positioning Design for IRS-assisted MISO System with Multiple Access Points
Authors: Chao Tang , Fung Carrson , Ni Zi-En , Servetnyk Mykola 
Published: October 2023

<p><code>Intelligent reflecting surface (IRS) is a promising concept for </code><code><u>6G</u></code><code> wireless communications that allows tuning of the wireless environments to increase spectral and energy efficiency. Many optimization techniques have been proposed in literature to deal with the joint passive and active </code><code><u>beamforming</u></code><code> design problem, but without any </code><code><u>optimality</u></code><code> guarantees for the multiple access points (</code><code><u>APs</u></code><code>), multiple </code><code><u>IRSs</u></code><code>, and multiple users scenario. Moreover, the multiple access problem is also considered with the </code><code><u>beamformer</u></code><code> design which has not been addressed in literature, except in the context of joint transmission, which is not considered herein. To further maximize ground based and support non-terrestrial communications, the joint aerial IRS (AIRS) positioning and </code><code><u>beamformer</u></code><code> design problem is also considered. </code></p>
<pre><code>In the first part of the paper, an algorithm considering predefined AP-user pairing is proposed, which allows <u>beamforming</u> vectors to be designed distributively at each access point by using Generalized Bender Decomposition (<u>GBD</u>), consequently resulting in certain level of <u>optimality</u>. The problem can be transformed via mathematical manipulation and <u>semidefinite</u> relaxation (<u>SDR</u>) into a convex problem and solve using <u>semidefinite</u> programming (<u>SDP</u>). Another algorithm was developed to solve for optimal AP-user pairing at the same time by introducing additional binary variables, making the problem into a mixed-integer <u>SDP</u> (<u>MISDP</u>) problem, which is solved using <u>GBD</u>-<u>MISDP</u> solver, albeit with higher computational and time complexity than the <u>GBD</u> for the original problem. A heuristic pairing algorithm, called <u>GBD</u>-iterative link removal (<u>GBD</u>-<u>ILR</u>), is proposed to combat this problem and it is shown to achieve solution close to that of the <u>GBD</u>-<u>MISDP</u> method. A joint AIRS positioning and <u>beamformer</u> design problem is solved in the second part by using the proposed successive convex approximation-alternating direction of method of multipliers-<u>GBD</u> (SAG) method. Simulation results show the effectiveness of all proposed algorithms for joint <u>beamformer</u> design, joint <u>beamformer</u> design with AP-user pairing in a multiple access points system, and the joint AIRS positioning and <u>beamformer</u> design. In addition to simulation results, an analysis of communication overhead incurred due to use of the IRS is also given.</code></pre>

Published: October 2023

Makala hii inashughulikia athari za Katama Mkangi kwa John Habwe kwa kujikita katika riwaya teule za Kiswahili za Mafuta (1984) na Cheche za Moto (2008). Utanzu wa riwaya ya Kiswahili umeendelea kupanuka kimaudhui na kifani kutokana na juhudi za watunzi mbalimbali kama vile Katama Mkangi na John Habwe. Japo tafiti za awali zimetafitia suala la mwingiliano matini, tafiti nyingi zimejikita katika kazi za mtunzi mmoja. Utafiti wa kina ulihitajika kuchunguza namna utunzi wa Mafuta (1984) ulivyoathiri John Habwe alipoitunga riwaya yake ya Cheche za Moto (2008). Katama Mkangi aliandika riwaya ya Mafuta katika wakati wa chama kimoja cha kisiasa ambapo uhuru wa kujieleza ulikuwa umebanwa sana. Habwe ameandika kazi yake katika mazingira yaleyale lakini katika kipindi ambapo uhuru wa kujieleza umepanuliwa. Kwa hivyo, amekwepa mtindo wa kimajazi alioutumia Mkangi na kuyaangazia masuala anayoyaibua kwa njia wazi. Makala hii ililenga kuonyesha kuwa maudhui katika riwaya ya Cheche za Moto ni mwangwi unaotokana na riwaya ya Mafuta (1984). Utafiti huu uliongozwa na nadharia ya mwingiliano matini iliyoasisiwa na Julia Kristeva (1969). Mihimili mikuu ya nadharia hii iliyoongoza utafiti huu ni pamoja na: hakuna matini ya fasihi yenye sifa za pekee, matini hubainisha sifa mbalimbali za matini tangulizi, na mwisho, matini ya baadaye huweza kufafanua dhana fulani kutoka matini tangulizi kwa njia inayoeleweka. Nadharia hii ya mwingiliano matini ilisaidia pakubwa kuonyesha namna kazi ya awali, Mafuta (1984) ilivyomwathiri John Habwe katika utunzi wa Cheche za Moto (2008) kimaudhui. Riwaya teule ziliteuliwa kimakusudi ili kupata sampuli faafu yenye data ya kujaza pengo la utafiti. Data ilikusanywa kupitia kwa usomaji wa maktabani na vilevile kusakura mitandaoni kuhusu vipengele vya mwingiliano matini katika riwaya ya Kiswahili. Data hii imewasilishwa kwa njia ya kimaelezo. Utafiti wa makala hii unatarajiwa kutoa mchango katika uhakiki wa utanzu wa riwaya ya Kiswahili, hususan kuhusu kipengele cha kuathiriana baina ya watunzi wa riwaya za Kiswahili

Polaritätenprofile und Geruchsscore – eine neue Methode zur Klassifikation von hedonisch eindeutig angenehmen Anlagengerüchen/Polarity profiles & odour score – a new method for the classification of hedonic definitely pleasant facility odours
Authors: Franzen-Reuter Isabelle , Mannebeck Bettina , Müller Frank , Niebaum Anke , Sucker Kirsten , Both Ralf , Kwiatkowski Kathrin , Bischoff Michael , Broer Lars 
Published: October 2023

Die Methode der Polaritätenprofile dient zur Feststellung eindeutig angenehmer Anlagengerüche und wird zur hedonischen Klassifikation von Anlagengerüchen gemäß Anhang 7 der Technischen Anleitung zur Reinhaltung der Luft (TA Luft) angewendet. Im Falle hedonisch eindeutig angenehmer Gerüche besteht die Möglichkeit, deren Beitrag zur Gesamtbelastung mit dem Faktor 0,5 zu gewichten.

Bislang wurde die Entscheidung auf Basis von zwei Korrelationskoeffizienten getroffen: die Korrelation des Anlagengeruchs mit dem Duft-Profil (> +0,5) und mit dem Gestank-Profil (< -0,5). Erfüllte ein Anlagengeruch nur eines dieser beiden Kriterien, durfte der Faktor 0,5 nicht angewendet werden.

Außerdem lässt sich anhand der Korrelationskoeffizienten nicht erkennen, ob es sich um einen Anlagengeruch handelt, der nur von einigen Personen als unangenehm, aber von anderen als angenehm beurteilt wird, wie am Beispiel Rinderstall gezeigt wird. Dies war Anlass, um im Rahmen des Forschungsprojekts „Immissionsschutz und Tierwohl“ von der Technischen Universität Dortmund im Auftrag des Landesamtes für Natur, Umwelt und Verbraucherschutz Nordrhein-Westfalen (LANUV NRW) ein alternatives Auswerteverfahren für die Methode der Polaritätenprofile zu entwickeln. Mit der neuen Methode der Geruchsscores kann nun anhand eines einzigen Zahlenwertes und des damit verbundenen statistischen Verfahrens klar entschieden werden, ob es sich um einen hedonisch eindeutig angenehmen Anlagengeruch handelt. Darüber hinaus ermöglicht die neue Methode eine detaillierte Analyse aller individuellen Bewertungen, sodass erkennbar wird, ob ein Anlagengeruch möglicherweise nur von einigen Personen als unangenehm, von anderen aber als angenehm empfunden wird. Im Rahmen der aktuellen Überarbeitung wird die neue Methode der Geruchsscores in die Richtlinie VDI 3940 Blatt 4 aufgenommen.
Gaze shifts during wayfinding decisions
Authors: Geisen Mai , Bock Otmar , Klatt Stefanie 
Published: October 2023

AbstractWhen following a route through a building or city, we must decide at every intersection in which direction to proceed. The present study investigates whether such decisions are preceded by a gradual gaze shift in the eventually chosen direction. Participants were instructed to repeatedly follow a route through a sequence of rooms by choosing, in each room, the correct door from among three possible doors. All rooms looked alike, except for a room-specific cue, which participants could associate with the direction to take. We found that on 88.9% of trials, the gaze shifted from the cue to the chosen door by a single saccade, without interim fixations. On the few trials where interim fixations occurred, their spatiotemporal characteristics differed significantly from that expected in case of a consistent shift. Both findings concordantly provide no support for the hypothesized gradual gaze shift. The infrequent interim fixations might rather serve the purpose to avoid large-amplitude saccades between cue and door.

Hasil percobaan menunjukkan bahwa penambahan konsentrasi Ca(NO3)2 berpengaruh terhadap pertumbuhan dan hasil tanaman kale, pakcoy, dan selada yang dibudidayakan dengan teknik hidroponik DFT. Konsentrasi Ca(NO3)2 yang optimum untuk tanaman kale yaitu sebesar 249,29 ppm, untuk tanaman pakcoy yaitu sebesar 260 ppm dan untuk tanaman selada sebesar 171,25 ppm.
RESEARCH WORK ON THE DRIED BOTTOM OF THE ARAL SEA

Published: October 2023

The Aral ecological crisis occupies a special place among global problems and is the result of the largest human meddling in the environment on the planet. The shrinking of the Aral Sea exposed another global catastrophe: anthropogenic desertification.
Before the Aral Sea began to dry up, it was considered to be the fourth biggest lake in the world by area after the Caspian Sea, Lake Superior (North America), and Lake Victoria (Africa). The degradation of the Aral Sea began in the 1960s when larger portions of the Syr Darya and Amu Darya were diverted for irrigation and to provide for the household needs of Turkmenistan, Uzbekistan, and southern Kazakhstan. As a result, the sea significantly withdrew from its shores and exposed the seabed, which was covered in sea salts contaminated by pesticides and other chemicals [1,2].
In today’s day and age, desertification is one of the world’s most serious problems. Desertification bears unexpected and undesirable consequences for mankind. The increasing land degradation accelerates the lowering of agricultural yields, which will eventually lead to the impoverishment of the local population and will cause people to migrate from their homes. For this reason, desertification is one of the most worrisome problems facing mankind today. The mitigation of the consequences of desertification can only be done by the application of large-scale action on the national and international levels with the participation of private investors.

Published: October 2023

В ходе выполнения исследовательских работ разработана технология производства смузи «Очищающий», «Мочегонный», «Желчегонный», «Успокаивающий» и «Тонизирующий» на основе плодов бахчевых культур с обогащающими добавками растительного происхождения. При разработке рецептуры смузи на основе плодов бахчевых культур особое внимание уделялось органолептическим показателям, а подбор компонентов определялся исходя из функциональной направленности смузи (очищающие, мочегонные, желчегонные, успокаивающие и тонизирующие) с использованием обогащающих добавок растительного происхождения. В процессе производства смузи в резервуар-смеситель из нержавеющей стали загружают основное сырье и обогащающие добавки растительного происхождения и тщательно перемешивают до однородной массы на гомогенизаторах Р = 15-17 МПа. После гомогенизации смузи разливают в пакеты из многослойной полиэтиленовой пленки и замораживают в морозильных установках при температуре – 30÷– 40°С в течение часа. Гомогенизированные смузи перед розливом подвергают деаэрации в деаэраторах-пастеризаторах при температуре t = 35-40°С и давлении Рост. = 6-8 кПа в течение 10 мин, в вакуум-аппаратах при температуре t = 45-50°С и давлении Рост. = 11-17 кПа в течение 10 мин и подогреванию до температуры t = 70-80°С. Розлив смузи производят в тетрапакеты массовой вместимостью до 500 мл и укупоривают. После замораживания смузи в пакетах из многослойной полиэтиленовой пленки подают в холодильные камеры, где они могут храниться при температуре –18ºС в течении 12 месяцев. Хранение смузи в тетрапакетах осуществляется при температуре 0-15ºС в течении 12 месяцев. Использование разработанной технологии смузи на основе плодов бахчевых культур с обогащающими добавками растительного происхождения позволяет расширить ассортимент диетических продуктов функциональной направленности.

Abstract
We present the spectroscopic confirmation and precise mass measurement of the warm giant planet TOI-199 b. This planet was first identified in TESS photometry and confirmed using ground-based photometry from ASTEP in Antarctica including a full 6.5 hr long transit, PEST, Hazelwood, and LCO; space photometry from NEOSSat; and radial velocities (RVs) from FEROS, HARPS, CORALIE, and CHIRON. Orbiting a late G-type star, TOI-199 b has a

The Physical Thickness of Stellar Disks to z ∼ 2
Authors: Hamilton-Campos Kathleen A. , Simons Raymond C. , Peeples Molly S. , Snyder Gregory F. , Heckman Timothy M. 
Published: October 2023

Abstract
In local disk galaxies such as our Milky Way, older stars generally inhabit a thicker disk than their younger counterparts. Two competing models have attempted to explain this result: one in which stars first form in thin disks that gradually thicken with time through dynamical heating, and one in which stars form in thick disks at early times and in progressively thinner disks at later times. We use a direct measure of the thicknesses of stellar disks at high redshift to discriminate between these scenarios. Using legacy Hubble Space Telescope imaging from the CANDELS and GOODS surveys, we measure the rest-optical scale heights of 491 edge-on disk galaxies spanning 0.4 ≤ z ≤ 2.5. We measure a median intrinsic scale height for the full sample of 0.74 ± 0.03 kpc, with little redshift evolution of both the population median and scatter. The median is consistent with the thick disk of the Milky Way today (0.6–1.1 kpc), but it is smaller than the median scale height of local disks (∼1.5 kpc) that are matched to our high-redshift sample by descendant mass. These findings indicate that, while (1) disks as thick as the Milky Way’s thick disk were in place at early times, (2) to explain the full disk galaxy population today, the stellar disks in galaxies need to on average physically thicken after formation.
Dynamics of Photospheric Magnetic Flux Distribution and Variations in Solar RVs: A Study Using HARPS-N Solar and SDO Observations
Authors: Sen Anisha , Rajaguru S. P. 
Published: October 2023

Abstract
The distribution and evolution of photospheric magnetic fields in sunspots, plages, and network, and variations in their relative flux content, play key roles in radial velocity (RV) fluctuations observed in Sun-as-a-star spectra. Differentiating and disentangling such magnetic contributions to RVs help in building models to account for stellar activity signals in high-precision RV exoplanet searches. In this work, as earlier authors, we employ high-resolution images of the solar magnetic field and continuum intensities from SDO/HMI to understand the activity contributions to RVs from HARPS-N solar observations. Using well-observed physical relationships between strengths and fluxes of photospheric magnetic fields, we show that the strong fields (spots, plages, and network) and the weak inter-network fields leave distinguishing features in their contributions to the RV variability. We also find that the fill factors and average unsigned magnetic fluxes of different features correlate differently with the RVs and hence warrant care in employing either of them as a proxy for RV variations. In addition, we examine disk-averaged UV intensities at 1600 and 1700 Å wavelength bands imaged by SDO/AIA and their performances as proxies for variations in different magnetic features. We find that the UV intensities provide a better measure of contributions of plage fields to RVs than the Ca ii H-K emission indices, especially during high activity levels when the latter tend to saturate.
