Evaluation of the biological effectiveness of the biofungicide Serenade ASO, SC in the fight against bacterial black spot of tomatoes (Xanthomonas campestris pv. vesicatoria (Doidge) on indoor tomatoes
Authors: Volodin V.A. , Shadura N.I. , Stranishevskaya E.P. , Matveikina E.A.
Published: September 2023

The article presents the results of two-year studies on the biological effectiveness of biofungicide Serenade, ASO, SC (Bacillus amyloliquefaciens, strain QST-713, titer not less than 1x10 9 CFU/ml) in the fight against bacterial black spot on the leaves and fruits of indoor tomatoes in the conditions of the II soil-climatic zone of the Crimea. It was found that a five-time treatment with biofungicide Serenade, ASO, SC, the rate of application of 5.0, 6.5 and 8.0 l/ha, contributed to a decrease in the intensity of development of Xanthomonas campestris pv. vesicatoria on leaves by 2.3-2.9 times, on fruits by 2.2-2.7 times. On the 10th day after the fifth spraying, the biological effectiveness of biofungicide Serenade, ASO, SC in the application rates of 5.0, 6.5 and 8.0 l/ha, with an average development of bacterial black spot on the control variant (3.3-5.2% on leaves, 2.9-3.3% on fruits), on leaves was 76.5-85.1%, on fruits – 71.6-75.0%. On the day of the last harvest, on the 29th day after the last treatment, the biological efficiency on leaves was 57.3-65.4%, on fruits – 54.5-62.6%. The difference of five-time treatment with biofungicide Serenade, ASO, SC in the norm of application of 8.0 l/ha, with the standard is insignificant, within the limits of experimental error. The positive effect of biofungicide Serenade, ASO, SC on yield was noted. The difference with the control (77.9 c/ha) is 34.9, 36.9 and 41.0 c/ha.

Authors: Sevryugina Nadezhda , Apatenko Aleksey , Fomin Aleksandr
Published: September 2023

The technologies for implementing the tasks of involving fallow lands in agricultural turnover and increasing the fertility of agricultural lands in the long-term period of economic activity are highlighted. Insufficient informativeness of the use of yield maps to assess the fertility of fields has been revealed. It is proposed to use field relief maps to establish the dynamics of violation of the water-air regime of the soil. It is proved that in the process of involving fallow lands into circulation, it is necessary to introduce a technological operation of microtopographic analysis of the degree of soil moisture. An algorithm for enabling the operation of levelling of field surface (removal of relief) using modern positioning systems has been developed. It was revealed that the levelling of the field with a laser level allowed to reduce yield fluctuations by 20% within the crop acres of the field and increase yield by 25-30%. Disadvantages of positioning accuracy with the use of laser and satellite positioning have been established. It is proposed to transfer digital information transmission modules to network clusters with the choice of the best digital data transmission channel by including an uninterrupted positioning module with digital data transmission over a 434 MHz and 864 MHz radio channel with a range of up to 600 meters to other modules for providing digital positioning information to the machine. The plan of implementation of the concept of digital field formation on the basis of the field experimental station of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy is presented, with the aim of creating a frontier for the sustainable development of closed-life cycle technologies through the introduction of innovations using multiplicative interaction of mechatronic systems and telematics for agricultural technology.

Authors: Zabolotskaya Tatyana , Staufen Alexandra , Smirnova Ekaterina , Ivannikova Regina
Published: September 2023

To ensure the safety of the drugs being developed and their guaranteed effectiveness, large-scale experiments using sufficient groups and types of test objects are required. The composition of the studied preparation, which includes the main representatives of rhizospheric microorganisms sorbed on mineral sorbent, allows us to judge its environmental safety. At the same time, the preparations offered for organic farming should have sufficient effectiveness, stimulating the growth and development of cultivated plants. The article presents the results of an experimental study and analyzes the effect of the mineral-biological drug Glauxin on the intensity of development of a test culture – Lettuce variety «Vostorg». The formed groups of experience and control, and identical growing conditions made it possible to obtain objective data, and the number of test objects in the groups (n=50) was sufficient for statistical processing of the results obtained. To obtain the most complete picture of the effect of the drug being developed, observations were carried out for 60 days, which exceeds the productive period of this culture by 15 days. To determine the most effective ways of using the drug Glauxin, two treatment schemes were applied to the tested plants: with soaking of seeds and without pre-soaking, using the studied drug only when watering and spraying. The results obtained indicate a high stimulating activity of the drug, allow us to judge its safety, because in the recommended modes of use they do not cause physiological changes and violations of the development of the test culture of lettuce. Based on the results obtained, conclusions were drawn about the most effective method of using the mineral-biological drug Glauxin, statistical data processing will allow us to draw conclusions about the economic efficiency of its use on an industrial scale.

Authors: Vendin Sergey , Strakhov Vladimir , Manuilenko Alexander
Published: September 2023

The results of studies on the use of UV treatment for the disinfection of soybean seeds from pathogenic microflora before sowing are presented. The research is devoted to the development of a technology for preparing seeds before sowing, which involves pre-treatment of seeds with UV radiation, followed by treatment with traditional chemical and biological means of protecting seeds from pathogenic microflora. The research was aimed at establishing the relationship between the parameters of UV treatment and the effectiveness of surface disinfection of seeds. The object of experimental studies was the seeds of soybean variety «Nezhegol». The influence of such influencing factors as the energy illumination of the surface under UV irradiation and the duration of UV irradiation was studied. As a function of the response to UV exposure, the total number of microbial cells (CFU/g) after treatment was taken. It has been established that seed treatment with UV radiation provides effective disinfection of the seed surface. The number of microbial cells on the soybean surface after UV treatment decreased by 99% compared to the control. For the disinfection of soybean seeds, it is possible to recommend a treatment mode with an energy illumination of UV irradiation of 9 W/m2 and a minimum duration of UV irradiation of 30 s. Specific energy costs for UV treatment range from 1.16·10-4 kW·h/m2 to 2.25·10-4 kW·h/m2.

Published: September 2023

This article presents some results of analysis of the biologically active food additives market, dietary supplement consumer groups. It was revealed that the most responsive consumers of new products, including dietary supplements, are young people under the age of 35, primarily students of higher educational institutions. Based on the results of these studies and studies of rheological and organoleptic characteristics of chocolate mass and finished product, the composition of the chocolate truffles enriched with fish oil and dietary fiber was developed and patented. Wild Kamchatka salmon fish oil is used as an enriching component in chocolate truffles, rich in polyunsaturated fatty acids (eicosapentaenoic and docosahexaenoic acids), as well as wheat fiber - a source of dietary fiber. The developed composition was tested in production conditions using the technology described in the article.
Variational Problems in L∞ Involving Semilinear Second Order Differential Operators
Authors: Katzourakis Nikos , Moser Roger
Published: September 2023

For an elliptic, semilinear differential operator of the form S(u) = A : D2u + b(x, u, Du), consider the functional E∞(u) = ess supΩ, |S(u)|. We study minimisers of E∞ for prescribed boundary data. Because the functional is not differentiable, this problem does not give rise to a conventional Euler-Lagrange equation. Under certain conditions, we can nevertheless give a system of partial differential equations that all minimisers must satisfy. Moreover, the condition is equivalent to a weaker version of the variational problem. The theory of partial differential equations therefore becomes available for the study of a large class of variational problems in L∞ for the first time.

Authors: Agil Jonathan , Letourneur Bruno , George Sylvie , Battesti Rémy , Rizzo Carlo
Published: September 2023

In this paper, first we present a review of experimental data corresponding to phase retardation per reflection of interferential mirrors. Then, we report our new measurements on both commercial and tailor-made mirrors. To be able to measure the phase retardation as a function of the number of layers, additional pairs of layers are deposited on some of the mirrors. The results obtained with this special set of mirrors allow us to fully characterise the waveplate associated with the additional pairs of layers. We finally implemented a computational study whose results are compared with the experimental ones. Thanks to the additional layers, we have achieved reflectivity never measured before at λ = 1064 nm, with an associated finesse of F = 895 000.

Authors: Lagente M. , Barthelemy R. , de la Farge F. , Dedieu G. , Puel P. , Enjalbert A. , Valdiguh P.
Published: September 2023

The amount of Di-2-Ethyl Hexyl Phthalate (DEHP) released from the components of Extra Corporeal Circulation (ECC) systems is studied in vitro, ex vivo and in vivo experiments.

The in vitro and ex vivo studies showed that the ester is released from the Polyvinyl Chloride (PVC) used. For the in vivo study, 55 patients {vere divided into two groups. Both groups each used a different oxygenator (either a TMO or a BOS 10). Immediately after surgery a significant increase in DEHP was observed. After a 24 hours period (without ECC) the amount decreased.

A significant difference in the total phthalate ester content between the two groups revealed that the TMO patients had a higher DEHP blood level concentration than those using the BOS I 0 oxygenator.
One Hundred Consecutive Perfusions Over Five Hours
Authors: Peters Jeffrey , Sparacino Michael
Published: September 2023

Complete surgical treatment of severe, diffuse coronary artery disease requires long perfusion time. We reviewed 100 consecutive perfusions longer than five hours (from a total of 675, operated May, 1980, through May, [1981]). No case was excluded.

The 100 patients received 517 grafts, 217 coronary endarterectomies, 12 valves, and 12 aneurysmectomies; 98 had three vessel disease and 22 severe ventricular dysfunction. High flow, high pressure perfusion with physiologic blood gases was used.

Filters were used on cardiotomy return and arterial lines. Body temperature was kept 30–34°C at the preference of the surgeon. Intermittent ischemic arrest was used to preserve the myocardium. There were nine hospital deaths. Complications in the survivors included two instances of adult respiratory distress syndrome, one instance of stroke, and one of perioperative infarction. No patients were taken back for postoperative bleeding.

We conclude that, in view of the severity of disease, deaths and complications were well within acceptable limits.

Long perfusions, greater than five hours, did not contribute significantly to morbidity and mortality. Patients were perfused as long as necessary to achieve total revascularization.

Hemoglobin P50 Dynamics During Hypothermic Cardiopulmonary Bypass
Authors: Riley Jeffrey B. , Palmer-Steele Candace L.
Published: September 2023

The hemoglobin P50 was ascertained prior to anesthesia and CPB and calculated during hypothermic CPB to track the change in hemoglobin affinity in fifty randomly selected cardiac disease patients.

The AMINCO Hem-0-Scan standardized P50 averaged 32.1 +/− 6.8 (1 SD) mmHg in the awake, slightly sedated CPB candidate. The awake patients were distributed into three significantly different (p < .05) groups: left-shifted oxyhemoglobin dissociation curve (ODC), P50 = 23.1 ±/− 1.4, n = 5; normal ODC, P50 = 27.2 ±/− 1.3, n = 13; and right-shifted ODC, P50 = 35.4 ±/− 6.1, n = 32. The three groups converged at the termination of hypothermic CPB to a single group calculated, mean P50 = 30.7 ±/− 4.7 mmHg.

Unlike the previous studies of Woodson2 (1970) and Wilkinson (1979), the Hem-O-Scan pre-CPB P50 demonstrated a weak inverse correlation to ejection fraction, cardiac index and hemoglobin flow index in this patient group. The position of the ODC prior to and during CPB may not be accurately predicted. Therefore, direct measurement of pO2 and O2 saturation of hemoglobin is recommended and calculator prediction of hemoglobin O2 saturation from pO2 assuming a beginning P50 = 27 mmHg may not be trusted in cardiac diseased patients.
Traumatismes des incisives et auto-transplantation
Authors: Sorel Olivier
Published: September 2023

Un européen sur deux est victime d’un traumatisme dentaire souvent compliqué par une expulsion dentaire ou une luxation compromettant la conservation des dents. La réhabilitation implantaire est contre-indiquée avant les 20 25 ans du patient.

L’auto-transplantation est alors un recours notamment chez l’enfant : la racine transplantée est un véritable « implant » biologique qui évolue harmonieusement avec l’environnement en croissance.

Elle nécessite un transplant qui, le plus souvent, est une prémolaire. Dans le parcours de soins, après traumatisme dentaire, quand elle est possible, la réimplantation est le premier recours. La situation peut se compliquer : ankylose résorption infection... entraînant la nécessité d’extraire. La réimplantation peut permettre d’attendre l’évolution de la racine de la dent à transplanter.

Le protocole d’auto-transplantation comprend deux temps opératoires. L’utilisation du CBCTpermet de programmer l’intervention et de réaliser une réplique du transplant ou clone par CFAO. Dans un premier temps, la néo-alvéole est préparée, guidée par le clone. Puis le transplant est délicatement mobilisé. Dans un deuxième temps, 10 jours après, la néoalvéole est réouverte et curetée, le transplant est prélevé et directement implanté; une contention par un fil de suture en croix le maintient.

La fiabilité de cette technique est comparable à celle des implants dentaires, avec de nombreux avantages.
Einfluss von Rasse und Herdengröße auf die
Intraherdenprävalenz von Salmonella enterica subspecies
diarizonae Serovar 61: k: 1, 5, (7) bei Schafen
Authors: Heinemann Lisa , Methner Ulrich , Klassen Anne , Donat Karsten , Moog Udo
Published: September 2023

Gegenstand und Ziel In Deutschland liegen derzeit nur wenige Informationen
über die Intraherdenprävalenz von Salmonella enterica
subspecies (ssp.) diarizonae Serovar 61: k: 1, 5, (7) (SASd) in
Schafherden und über deren mögliche Einflussfaktoren vor. Ziel
der Studie war es, Beziehungen zwischen der Herdengröße, der
Rasse und der Intraherdenprävalenz zu untersuchen.

Material und Methoden Insgesamt 1610 klinisch gesunde Mutterschafe aus 14
Schafherden mit 9 unterschiedlichen Rassen im Alter von 2 bis 12 Jahren wurden
mittels Nasenabstrich und Kotproben mikrobiologisch auf SASd untersucht.
Für die Analyse der Zusammenhänge zwischen der
Intraherdenprävalenz und den Betriebsfaktoren
(Bestandsgröße, Rasse) bzw. den Nachweishäufigkeiten in
Kot- bzw. Nasentupfern kamen lineare multivariable Modelle zum Einsatz.

Ergebnisse SASd wurde in allen untersuchten Herden nachgewiesen, wobei
75% der adulten Tiere mindestens ein positives Nasen- oder Kotresultat
aufwiesen. Im Vergleich zu den 11 Beständen, in denen Wirtschaftsrassen
gehalten wurden, wiesen 3 Herden, in denen Landrassen gehalten wurden, eine
geringere scheinbare Intraherdenprävalenz (p=0,01) auf. Es
bestand keine Beziehung zur Herdengröße. In Bezug auf das Alter
der Mutterschafe bestand eine negative Beziehung (p=0,05) zur
Nachweishäufigkeit von SASd im Nasentupfer, jedoch nicht im Kottupfer.
Der Gesundheitszustand und die Fruchtbarkeitsleistung der Herden entsprachen mit
5% bis 10% Lämmerverlusten und einem Ablammergebnis von
130% bis 158% einem für kommerzielle Schafherden
normalen Bereich.

Schlussfolgerungen Trotz der hohen Verbreitung von SASd innerhalb der
Wirtschaftsrassen ist nicht von einem erheblichen Risiko für die
Gesundheit von Schafen auszugehen. Im Vergleich zu Herden kommerzieller Rassen
ist die Verbreitung von SASd in Herden, die Landrassen halten, geringer.

Klinische Relevanz Infektionen mit SASd führen trotz starker
Verbreitung mit hoher Wahrscheinlichkeit nur in sehr selten Fällen zu
einer klinischen Symptomatik. Die Bekämpfung und Überwachung von
SASd bei Schafen ist für die Tiergesundheitsbehörden von
geringer Priorität.

Die Evaluation eines sportorientierten Schulungsprogramms zur
Befähigung eines selbstregulierten Trainings für Menschen mit
Multipler Sklerose
Authors: Morvilius S. , Woschek S. , Schubert P. , Wagner P. , Lutz C. , Beaudouin F. , Haas C. T.
Published: September 2023

Hintergrund Studien belegen einen positiven Nutzen von Sport auf Multiple
Sklerose (MS). Eine 2014 für Personen mit Multipler Sklerose (PmMS)
entwickelte sportorientierte Kompaktschulung (SpoKs) soll den Zugang zu
selbstreguliertem sportlichen Training eröffnen. Sie bedient den Mangel
an sportorientierten Schulungskonzepten zur Befähigung des
selbstregulierten Trainings für MS und wurde bislang durch 3
aufeinanderfolgende Studien unterschiedlicher Designs und Probandenpools
evaluiert.

Ziel In dieser Umsetzungsstudie soll der Einfluss der SpoKs (von Juni 2017
bis Mai 2019) auf die motorische Leistungsfähigkeit, Fatiguesymptomatik,
Depressionsausprägung, Lebensqualität, Ausmaß der
Selbstmanagementfähigkeit, Selbstwirksamkeit sportlicher
Aktivität und Verständlichkeit aus Probandensicht erhoben
werden. Die Daten sollen mit den bereits publizierten Studienergebnissen in
Vergleich gesetzt und die Aussagekraft bisheriger Erkenntnisse soll durch
Erhöhung der Probandenmenge verbessert werden. Zudem sollen
zusätzliche Assessments das Wissen um die Auswirkung der SpoKs
erweitern.

Methode Das Wochenend-Workshop-Design der SpoKs mit 2 Wochenendschulungen
befähigte die Teilnehmenden (n=123) zum anschließenden
selbstregulierten Training. Erhebungen fanden am ersten Schulungstag (T0) sowie
nach einer Eigentrainingsphase von 12 Wochen (T1) statt. Inhalte der Erhebung
waren das Functional Gait Assessment (FGA), der 6-Minuten-Walking-Test (6MWT),
der 10-Meter-Walking-Test (10MWT), die Fatigue Scale für Motorik und
Kognition (FSMC), die Selbstwirksamkeitsskala bei sportlicher Aktivität
(SSA), die Messung der Lebensqualität (MusiQol), die
MS-Selbstmanagement-Skala (MSSS), das Beck Depression Inventory (BDI-II) und der
Evaluationsbogen zur Verständlichkeit von Patientenschulungen
(COHEP).

Ergebnisse Es zeigte sich eine Verbesserung der motorischen
Fähigkeiten: FGA=17,95% (p=,001);
6MWT=18,10% (p=,19); 10MWT=5,00%
(p=,001) sowie des BDI-II um 21,70% (p=,08). Die MSSS
(p=,98) und der FSMC (p=,72) zeigten keine Unterschiede.
Reduzierte Werte zeigten die SSA (1,68%) und der MusiQol (2 Punkte).

Schlussfolgerung Die Ergebnisse dieser Studie konnten teils zur
Bestätigung, aber auch zur kritischen Auseinandersetzung bereits
erhobener Daten beitragen. Sie zeigten in Teilaspekten der Erhebung neue
Erkenntnisse auf. Das Konzept der SpoKs zeigte positiven Nutzen für die
PmMS und wurde von denselben ebenfalls positiv bewertet. Bisherige Ergebnisse
sollten über Erhebungen großer Probandengruppen über
Langzeiteffekte evaluiert und erweitert werden.

Published: September 2023

Hintergrund Unsere Bevölkerung ist vielfältig.
Diversitätsmerkmale wie ein Migrationshintergrund, das Alter oder das
Geschlecht gehen mit einer Vielzahl von Erwartungen an die
Gesundheitsversorgung, einschließlich der Rehabilitation, einher. Durch
eine diversitätssensible Versorgungsgestaltung ist es möglich,
diese Vielfalt zu berücksichtigen, was sich positiv auf die
Inanspruchnahme und die Ergebnisse der Versorgung auswirken kann.
Diversitätssensibilität sollte sich dabei jedoch nicht nur auf
die Vielfalt der Rehabilitand*innen beziehen, denn auch die Vielfalt der
Belegschaft geht mit Chancen und Herausforderungen einher, die beachtet werden
müssen. Einrichtungsleitungen und Gesundheitspersonal sind sich der
Notwendigkeit einer diversitätssensiblen Versorgung durchaus bewusst,
entsprechende Maßnahmen werden bisher aber selten und nur unsystematisch
angewendet. Ziel des Vorhabens war es, eine Handreichung – bestehend aus
einem Instrumentenkatalog und einem Handlungsleitfaden – zu entwickeln,
die Rehabilitationseinrichtungen bei der Umsetzung einer
diversitätssensiblen Versorgung unterstützen kann.

Methoden Für die Studie wurde ein Mixed-Methods-Ansatz verwendet.
Im Rahmen eines Scoping Reviews wurden zunächst geeignete Instrumente
für die Handreichung identifiziert (n=34), die zur Umsetzung
einer diversitätssensiblen Versorgung genutzt werden können. Ein
Entwurf der Handreichung wurde anschließend in sieben Fokusgruppen mit
Gesundheitspersonal (n=44) und einem Diskussionszirkel, bestehend aus
n=5 Vertreter*innen von Rehabilitationsträgern,
konsentiert.

Ergebnisse Die partizipativ entwickelte DiversityKAT-Handreichung
stellt diversitätssensible Instrumente vor, darunter Anleitungen,
Fragebögen, Checklisten und Konzepte, die dazu genutzt werden
können, die Vielfalt der Bedürfnisse und Erwartungen im
Versorgungsalltag zu berücksichtigen. Gemäß dem Feedback
des Gesundheitspersonals enthält die Handreichung einen
praxisorientieren Handlungsleitfaden, welcher in Form einer
Schritt-für-Schritt-Anleitung bei der Auswahl und Umsetzung geeigneter
Instrumente unterstützen soll. Auf Anregung des befragten Personals und
der Rehabilitationsträger wurden Fallbeispiele ergänzt, die den
Einsatz von beispielhaften Instrumenten in konkreten Situationen
veranschaulichen. Eine Auswahlmatrix dient zur schnellen Orientierung und der
Vorausauswahl geeigneter Instrumente.

Diskussion Durch praxisorientierte Hinweise und niedrigschwellige
Anleitungen besitzt die DiversityKAT-Handreichung das Potenzial, die
Nutzerorientierung in der Rehabilitation zu erhöhen, muss aber noch in
weiteren Evaluationsstudien überprüft werden.

Published: September 2023

Endoscopic ultrasound (EUS) has come a long way from mere diagnostic modality to performing interventional procedures like fine needle aspiration, gastric varices glue and coiling, and management of pancreatic fluid collection along with necrosectomy. Recently, EUS-guided biopsy of the liver has gained traction. This coupled with the ability to access the portal vein and measure portal pressure has made comprehensive liver evaluation possible using endoscopic route. In this review, we will discuss evolution and techniques of performing EUS-guided liver biopsy and portal pressure gradient. We will also compare the merits and demerits as compared with the other conventional techniques.
Spontaneous Intracranial Hypotension: A Review of Neuroimaging and Current Concepts
Authors: Goddu Govindappa Sharath Kumar , Adiga Chaitra Parameshwara , Kumar Savith , Goolahally Lakshmikanth N. , Kumar Sujit
Published: September 2023

Spontaneous intracranial hypotension (SICH) is the emerging cause of orthostatic headache as it has been better recognized in recent years. SICH happens due to spinal cerebrospinal fluid (CSF) leak; however, the manifestations are predominantly cranial and hence imaging in SICH includes brain and spine. There are few characteristic brain imaging features to be concerned about to diagnose SICH in patients with vague symptoms or low clinical suspicion. Spine screening is recommended in these patients to assess spinal CSF leaks. While neuroradiologists play a significant role from the time of diagnosis to treatment of SICH, there is a need for all the general radiologists to be aware of the condition. Computed tomography myelogram and digital subtraction myelogram are performed for diagnostic and therapeutic management of SICH. There is a known risk for SICH recurrence in patients with sagittal longitudinal epidural collection and hence, targeted blood patch should be used instead of blind patch. Most importantly, slow mobilization is recommended following the patch to avoid recurrence.
Pediatric Vascular Anomalies: A Clinical and Radiological Perspective
Authors: Gupta Rahul , Bhandari Anu , Navarro Oscar M.
Published: September 2023

According to the International Society for the Study of Vascular Anomalies (ISSVA) classification, vascular anomalies include a diverse range of pathologies, classified as either vascular tumors or vascular malformations. This classification, last revised in 2018, aims to explain the biological basis of vascular lesions and help clinicians to manage the anomalies. In vascular tumors, there are proliferative changes of endothelial cells, while vascular malformations primarily consist of structural vascular abnormalities. Infantile hemangioma is the most common soft-tissue vascular tumor. Vascular malformations are an extensive group of malformations of the arterial, venous, and lymphatic systems, either in isolation or in combination. Radiological evaluation plays a key part in the management of pediatric patients with these entities. The understanding of sonography and magnetic resonance imaging findings entails its correlation with clinical findings at the time of scanning.
Linguistic purification of violence in the press: a comparative critical discourse analysis of execution news
Authors: Bunnag Orawee , Chaemsaithong Krisda
Published: September 2023

The aim of this study is to probe for the discursive construction of shared beliefs about capital punishment. Drawing upon a specialized corpus of execution news, the study explores representational practices, including social actor naming, action description, and incorporation of voices, and compares respective lexico-grammatical choices that are orchestrated to reconstruct the events of executions in Thailand from 1997 to 2017. The findings reveal that these discursive choices purify state killing and hide the violence of state killing. While representation choices become less overtly negative over time, the underlying ideological position of the press has not changed. Throughout these periods, executions are represented as a routine procedure by minimizing and/or concealing state agency and as a commensurate punishment for the executed individuals, while the law enforcement and justice systems in place are intertextually framed as unproblematic and effective in deterring crime, based on the perspectives of few elite sources. By way of demystifying subtle linguistic choices, this study makes transparent the way in which the press endorses, normalizes, and perpetuates favorable stances toward death penalty in a democratic society.
Arbitrary self-rotating beam array generated with the synthetic phase

Published: September 2023

In this Letter, the phase profile of the self-rotating beam is modified by introducing the radial shift factor c and the azimuthal shift factor θ0. The effect of the radial shift factor c on the corresponding intensity distribution is discussed. The results demonstrate that the focal-field intensity patterns of the modified self-rotating beams with different radial shift factors moved away from the center of the light field with the radial shift factor increased. The self-rotating beam array can be arranged arbitrarily along the azimuthal direction with a synthetic phase produced by superimposing multiple modified subphases (i.e., modified self-rotating beam phase). Furthermore, the position of each self-rotating beam in the beam array can be also adjusted arbitrarily in the transverse plane by adding the gratings into each subphase layer of the synthetic phase. The proposed beam array has potential applications in image transmission, data coding and decoding, and optical trapping.
Quantitative study on thermoreflectance linear relation
Authors: Meng Biwei , Ma Yunliang , Wang Xinhua , Yuan Chao
Published: September 2023

Standard thermoreflectance-based measurements have been routinely taken on thin metal transducer (Au or Al) deposited samples. This is based on the fundamental hypothesis that the reflectance change (ΔR/R) of the metal surface is directly and linearly related to the temperature change (ΔT), within a wide but finite temperature range (Trange). The quantitative study on Trange has been ignored for a long time, which would possibly cause severe measurement issues and impede the possible new applications that the thermoreflectance measurements are taken on new metals or even directly on non-metals. Here, we present an approach that combines multiple probe wavelengths’ nanosecond transient thermoreflectance technique with a transient temperature rise model to study the linear relation. This method enables fast and accurate determination of the Trange and the proportional coefficient (commonly called the thermoreflectance coefficient, Cth). We studied the commonly used metal transducers (Au and Al) and found that Au illuminated at 532 nm has a considerably larger Trange (from room T to at least 225 °C), with respect to Al illuminated at 785 nm (room T to 150 °C). The linear relationships of uncommon Ni and Ti metals are valid from room temperature to ∼115 °C, illuminated at 785 and 660 nm, respectively. Non-linearity was observed for Al, Ni, and Ti metals when the temperature was elevated above the quantified Trange. This method enables a facile and reliable platform to characterize thermoreflectance properties and better understand the mechanism of thermoreflectance linear relationship.

Fear neural circuits can recognize precisely threatening stimuli and enable the early-warning for the individual in the real world. In this regard, implementation of fear neural circuits functions by neuromorphic devices could potentially improve the intelligent adaptability and cognition of humanoid robots. Here, an artificial fear neural circuit is proposed, which consists of a noise triboelectric nanogenerator (N-TENG) and an amorphous indium gallium zinc oxide based photoelectronic neuromorphic transistor (IGZO-PNT). Such an artificial fear neural circuit collects sound wave and light signals from the N-TENG and a-IGZO channel, respectively, converts these signals to electrical signals and integrates them into excitatory postsynaptic currents by the IGZO-PNT. The innate-fear and learned-fear behaviors are emulated by our artificial fear neural circuit. Furthermore, as a proof of concept, the escape behavior after fear triggered is realized by using a vibrator. Our biomimetic design can promote the developments of next-generation photoelectronic neuromorphic systems and humanoid robots.

The fragmentation of fulminic acid, HCNO, after excitation and ionization of core electrons was investigated using Auger-electron–photoion coincidence spectroscopy. A considerable degree of site-selectivity is observed. Ionization of the carbon and oxygen 1s electron leads to around 70% CH+ + NO+, while ionization at the central N-atom produces only 37% CH+ + NO+, but preferentially forms O+ + HCN+ and O+ + CN+. The mass-selected Auger-electron spectra show that these fragments are associated with higher binding energy final states. Furthermore, ionization of the C 1s electron leads to a higher propensity for C–H bond fission compared to O 1s ionization. Following resonant Auger–Meitner decay after 1s → 3π excitation, 12 different ionic products are formed. At the C 1s edge, the parent ion HCNO+ is significantly more stable compared to the other two edges, which we also attribute to the higher contribution of final states with low binding energies in the C 1s resonant Auger electron spectra.

Photocurrent in quantum materials is often collected at global contacts far away from the initial photoexcitation. This collection process is highly nonlocal. It involves an intricate spatial pattern of photocurrent flow (streamlines) away from its primary photoexcitation that depends sensitively on the configuration of current collecting contacts as well as the spatial nonuniformity and tensor structure of conductivity. Direct imaging to track photocurrent streamlines is challenging. Here, we demonstrate a microscopy method to image photocurrent streamlines through ultrathin heterostructure devices comprising platinum on yttrium iron garnet (YIG). We accomplish this by combining scanning photovoltage microscopy with a uniform rotating magnetic field. Here, local photocurrent is generated through a photo-Nernst type effect with its direction controlled by the external magnetic field. This enables the mapping of photocurrent streamlines in a variety of geometries that include conventional Hall bar-type devices, but also unconventional wing-shaped devices called electrofoils. In these, we find that photocurrent streamlines display contortion, compression, and expansion behavior depending on the shape and angle of attack of the electrofoil devices, much in the same way as tracers in a wind tunnel map the flow of air around an aerodynamic airfoil. This affords a powerful tool to visualize and characterize charge flow in optoelectronic devices.

As we encounter many disasters and crises worldwide, various forms of crisis intervention are utilized to assist those who are impacted. In the United States, animal-assisted crisis response (AACR), the use of highly trained and experienced therapy dogs to provide comfort and support to those in need, is becoming an essential post-crisis modality. However, maintaining qualified volunteers is challenging and research on the characteristics of AACR teams has been narrowly developed. Therefore, there is a growing need to better understand these specialized volunteer teams, both handlers and their canine partners.

This exploratory survey of 99 animal-assisted crisis responders investigated the qualities, backgrounds, perceptions, and experiences of these canine handlers and their dogs. Results from an online questionnaire showed that most handlers were women (88%), and the prevalent age range was 61–70 (45%). Most handlers were retired (46.46%) with an average volunteer experience in AACR of 5.7 years. The recognition of dominant organizations providing AACR was also studied in this research. Most volunteers were members of HOPE AACR (54.36%). Handlers shared their education, specific traits, and skills to provide effective AACR. The characteristics of the canine partners of AACR were also explored. The most common breeds for AACR teams were Golden retrievers (28.88%) and Labrador retrievers (18.88%). The authors additionally explored the handlers and the traits of their dogs, as well as their reason for volunteering in AACR. All participants viewed AACR as effective with most of the teams (80.68%) perceiving AACR as a highly effective intervention following crises and disasters. This research offers insights for AACR organizations on strategies to recruit and retain these specialized crisis providers.

Passivation makes 2D hexagonal structure more stable than the planar variant. Surface fluorinated monolayer of GaN have been found to have ultra-wide band gap and have promising applications in optoelectronic conversion devices. In this work, using theoretical method, we have explored the thermal conductivity as well as the electronic structure of F–GaN. It has a low thermal conductivity of 7.67 W (mK)−1 due to the low group velocity and short phonon lifetime. The calculated direct band gap value is 4.63 eV, which could be modulated by strain and biaxial strain is found to more effective. Attractively, direct band gap can be maintained under tensile strain. Breakdown of symmetry by uniaxial strain lifts the band degeneracy of the VBM, which will lead to polarized light emission. The in-depth analysis shows that Ga–F as well as N–F bonds are strongly ionic, which is responsible for its low thermal conductivity and ultra-wide band gap.

Investigation of the equivalent circuit and performance of an ultrasonic transducer under a force load
Authors: Rao Zhongyu , Shi Dinghui , Ye Hongxian , Hu Xiaoping
Published: September 2023

In ultrasonic processing technology applications, the force load can cause a drift in the resonance frequency of the ultrasonic transducer and significantly reduce its mechanical quality factor. The traditional equivalent circuit of an ultrasonic transducer can only be used to calculate performance parameters without a force load but not with a force load. Based on Mason’s equivalent circuit, a new equivalent circuit for ultrasonic transducers under a force load is derived while considering the effects of the force load on the material parameters and various types of losses in piezoelectric ceramics. Furthermore, performance parameters are analyzed, such as the resonance frequency, effective electromechanical coupling coefficient, and mechanical quality factor. The ultrasonic transducer sample is produced and the experimental platform is constructed for applying force loads on the ultrasonic transducer. The theoretical model is verified by static loading on the ultrasonic transducer. The proposed equivalent circuit provides theoretical guidance for tracking the exact resonance frequency and performance parameters of force-loading ultrasonic transducers.

In concealed underground projects, pile foundations may cause severe engineering accidents owing to factors such as construction technology, geological conditions, and material properties. Accordingly, the construction industry has invariably focused on developing high-precision, distributed, and low-cost monitoring and disaster warning methods. Therefore, a new sensing material, sensor-enabled piezoelectric geocable (SPGC), was developed to monitor the deformation and failure of a pile foundation. Three model piles were constructed, and packaging and layout processes for the SPGC sensing material were proposed. Moreover, a fiber Bragg grating (FBG) sensor and resistance strain gauge were installed for comparison. Pile foundation failure and static load tests were performed using a large servo hydraulic press. The monitored effect was evaluated by obtaining the impedance and voltage signals of the SPGC. Pile foundation failure test results show that the mutation of impedance and voltage signals can be used as combined monitoring data, and the electrical signal of the SPGC can be used in three stages of early warning response. These findings ensure that pile foundation damage can be located, damage precursors can be identified, and timely warning can be provided. The static load test results indicate that the SPGC data are in good agreement with the FBG sensor and strain gauge data. The impedance of the SPGC increases linearly with the load. Accordingly, a linear calculation formula relating impedance and strain is derived. The research results are expected to provide a new technical method for pile foundation construction and long-term operation and maintenance monitoring.
