Published: June 2023

The objectives of this experiment were to evaluate the performance of two varieties of sunflower (Helianthus annuus L.)  with three plant densities (40, 50 and  60 thousands of  plants.ha-1.)  and estimate the phenotypic, genotypic and environment variation, phenotypic and genotypic coefficient of variation, heritability, stability and genetic resultant, for two seasons. The experiments were conducted during spring and fall seasons of 2013, using factorial experiment within RCBD with four replicates. The results showed the superiority of Shimoos variety, it gives seed yield 3.345 t.ha-1 compared with Aqmar variety which gave 2.375 t.ha-1 in spring season, at fall season Shimoos variety gave 6.265 t.ha-1, while Aqmar variety gave 5.379 t.ha-1. The yield increased with plant density increasing, it ranged from 2.425 to 3.222t.ha-1 in spring season and from 4.396 to 5.822t.ha-1 in fall season. The values of phenotypic stability were different according to differences between varieties and seasons. The high value was 93.75% for disc area followed by 90.13% for seed yield t.ha-1 for Aqmar in spring season and the higher value for Shimoos variety was 94.15 for disc area followed by 90.66% and 90.55% for 100 seed weight and number of seeds in disc respectively. . All values of genetic variation are higher than environment variation, and were closed to phenotypic variations for spring and fall seasons, except for seed number in disc in fall season which was less than environment variation. Hence the heritability for these traits were high and ranges from 63% for seed number in disc to 95% for shoot dry weight in spring season and from 33% for seed number in disc to 99.6% for disc area in fall season. So the genetic coefficient of variation for all traits is closed to phenotypic coefficient variation. The traits: plant growth rate and shoot dry weight for Aqmar, and leaf area index, plant growth rate and seeds yield for Shimoos showed non phenotypic stability in spring season. In fall season, seed yield t.ha-1 for Aqmar was the only trait non-phenotypic stable. The genetic results are ranged from 65.32% for shoot dry weight to 98.86% for seed number in disc for Aqmar and from 81.34% for seed number in disc to 114.79% for 100 seed weight for Shimoos in spring. In fall season, it ranges from 69.18 for leaf area index to 96.02% for seed number in disc for Aqmar and from 89.25% for seed number in disc to 107.32% for disc area for ShimoosIt is possible to conclude that Shimoos variety was superior in most of the traits. So we recommend planting Shimoos variety in the fall season, because it is more stable than Aqmar variety, while Aqmar variety can be cultivated in the spring season.

Tissue samples of placenta and aborted fetus were collected from aborted cow and preserved in 10% formalin buffered saline for routine histopathology stained with H&E and for immunohistochemistry to detect TNF-a marker. Pathological examination showed necrotic foci with abscesses mainly around site of invasive protozoa. Immuno-Molecular examination showed marked deposition of TNF marker in tissue, mainly brain of fetus, which refers to genetic damage in gene responsible for controlling TNF values. It is concluded that protozoal infection with Neospora caninum can cause  abortion in cattle at advanced stage (8th month ) of gestation with severe histopathological lesions on placenta as well as the brain of fetus. This case report is an update for the information presented in the Proceedings of the 3rd Scientific Conference of the Faculty of Veterinary Medicine / University of Kerbala on 10th April 2017.
The role of volatile organic compounds in the interactions between leafhopper Arbordiahussaini (Hemiptera: Cicadellidae) and grapevine leaves
Authors: Mohammed Youssif Ali , Ahmed Qasim , Arif Mokhtar Abdulsattar
Published: June 2023

The leafhopper Arbordiahussaini can seriously destroy grapevines and is susceptible to the infestation of leafhopper. Volatile organic compounds (VOCs) released from uninfested and infested Kamali grape leaves were identified in this study. VOCs released from leaves were collected by the HS-SPME technique and analyzed by GC-MS. The results indicated that the infested leaves produce 19 VOCs; some VOCs were absent in uninfested because of the grape leafhopper infestation. VOCs were different between uninfested and infested leaves. The Olfactometer results showed leafhoppers preferred uninfested and infested leaves compared to filtered air treatment. Moreover, A. hussaini preferred infested leaves compared to uninfested ones. Our findings imply that these variations in VOCs are a crucial mediator in insect-plant interactions and may be employed in future research to pinpoint the primary substances that might be used as a lure for tracking and managing A. hussaini.

Best Practices for Addressing the Health Needs of the LGBTQ+ Community in Oncology Care
Authors: Bush Bláz , Chambers Raney Paula , Maingi Shail , Pratt-Chapman Mandi L. , Scout  , Goodman Clifford
Published: June 2023

Patients with cancer in the LGBTQ+ community experience worse health outcomes when compared with their non-LGBTQ+ peers because of a variety of factors, including stigma, underrepresentation in research, lack of support, and implicit bias on the part of clinicians. For generations, many LGBTQ+ people have feared disclosing their identity to providers, leading to gaps in care and even higher mortality. As more people are identifying as members of the LGBTQ+ community, it’s crucial for providers to recognize them appropriately in healthcare, take steps such as acknowledging chosen names and pronouns, and provide care free from judgment. In today’s political climate, members of this community are facing increasing scrutiny, challenges, and barriers to accessing safe and affirming care. Providers can do their part to improve health outcomes among LGBTQ+ people by making their practices known as safe and affirming spaces, working to increase inclusivity in oncology care and improving data collection.

Authors: Riely Gregory J.
Published: June 2023

The use of next-generation tyrosine kinase inhibitors has led to improved progression-free survival for patients with metastatic non–small cell lung cancer (NSCLC) and those with EGFR-mutant and ALK-positive tumors. Newer therapeutics can now target KRAS G12C mutations, EGFR exon 20 insertions, and ERBB2 (HER2) mutations. Patients with metastatic NSCLC should undergo molecular testing for these mutations as well as for BRAF mutations; MET exon 14 skipping alterations; and ROS1, RET, and NTRK gene rearrangements (fusions). Novel targeted therapeutics are emerging at a fast pace.
New First-Line Systemic Treatment Options for Metastatic Esophageal Squamous Cell Carcinoma
Authors: Gibson Michael K.
Published: June 2023

Esophageal squamous cell carcinoma is an aggressive malignancy with histologic variability depending on where in the world it is diagnosed, with most of these cancers occurring in China and other parts of Asia. Previous studies with cytotoxic chemotherapy combinations led to a plateau median overall survival of approximately 10 to 12 months, as well as a need for more effective treatment options. Cytotoxic chemotherapy served as the control arm in 3 studies that evaluated the safety and efficacy of immunotherapy + chemotherapy versus chemotherapy alone; in all 3 prospective randomized trials, the addition of immunotherapy resulted in a survival benefit in the first-line relapsed/metastatic setting. Data support these immunotherapy regimens as new standard-of-care systemic therapy options for unresectable, locally advanced, recurrent or metastatic esophageal cancers, and these regimens have now been incorporated into the NCCN Guidelines.

Tǔ (tierra) y yáng (océano): una dicotomía metafórica en el proceso de modernización de China
Authors: LI CHENG
Published: June 2023

Desde mediados del siglo XIX, época en que China entró en contacto intenso con Occidente, los conceptos geográficos tǔ (tierra o lo telúrico) y yáng (océano o lo marítimo) empezaron a adquirir una serie de connotaciones socioculturales que los convirtieron en una construcción metafórica de significación trascendental. El presente trabajo tiene como objetivo estudiar, desde la perspectiva de la Retórica Cultural, las relaciones interactivas entre los discursos generados en torno a la oposición tǔ-yáng y los profundos cambios producidos en el proceso de modernización de China. Tǔ y yáng, que representan identidades, actitudes, estilos de vida, ideologías y valores completamente diferentes, han dejado una profunda impronta en el lenguaje, el pensamiento y la cultura de la sociedad china. En términos generales, yáng se asocia con lo extranjero, lo moderno y lo atractivo, mientras que tǔ se refiere a lo autóctono, lo atrasado y lo rústico. No obstante, ambos conceptos sufren cambios semánticos y valorativos en distintos contextos sociales, lo cual atestigua las influencias mutuas entre el discurso y el poder, así como los vaivenes en las relaciones entre China y Occidente.
La alorrepetición como inicio de desacuerdo entre amigos y familiares
Authors: Villalba Ibáñez Cristina
Published: June 2023

Este artículo reflexiona acerca del patrón discursivo de alorrepetición con función de desacuerdo. El interés por este tipo de repeticiones no es novedoso (Bazzanella, 1993; Dumitrescu, 1990; Tannen, 1989), pero existen pocos trabajos que hayan abordado su estudio de forma singularizada. En este sentido, el presente trabajo parte de un corpus de conversaciones coloquiales entre familiares y amigos con el objetivo de hallar rasgos lingüísticos que ayuden a identificar este tipo de patrones discursivos. Además, también se caracteriza la naturaleza de los desacuerdos codificados mediante las alorrepeticiones. Los resultados muestran que la presencia de secuencias de justificación, de pronombres interrogativos/exclamativos y partículas discursivas especializadas en codificar sorpresa o marcar énfasis son altamente frecuentes en este tipo de enunciados para asegurar una correcta interpretación. Asimismo, los desacuerdos iniciados a partir de alorrepeticiones disentivas pueden adcribirse al plano epistémico (de forma preferente), si bien es cierto que también se han observado ejemplos donde el desacuerdo afecta al modo en que se codifica el mensaje o al desacuerdo con la acción enunciativa que se ha llevado a cabo en el turno anterior.

Motherese has been studied particularly in its prosodic features. The scientific literature has underlined the importance of this type of communication on the infants’ vocal responsiveness.  However, we still know little about the role of motherese on preterm infants’ vocal responsiveness. We intend to know the prosodic and communicative characteristics of motherese in preterm dyads and particularly to understand its relationship with the preterm infant’s vocal responsiveness. At NICU, mothers (N = 38) were asked to speak and to sing without words (humming) to their preterm infants in kangaroo care during five periods of three minutes alternating voice and silence, controlling the order effect (silence – speech or humming – silence – humming or speech – silence). A microanalytical study about prosodic and communicative/affectionate features of motherese was performed using ELAN, MAXQDA, and PRAAT software. According to results, tonal contours (sinusoidal, U-shaped and falling) and infants’ vocalizations seem to contribute for preterm dyads’ vocal modulation. A high use of phatic and conative functions, interrogative utterances, infants’ positive aspects, infants designated by affectionate words, and utterances connected with infants' needs were observed. This study contributed to explore the role of the communicative/affectionate and prosodic features of the motherese on preterm infants’ vocal responsiveness during the kangaroo care in NICU. Still, more studies are needed to deepen these preliminary results.

У руралном простору Босне и Херцеговине (БиХ) / Републике Српске (РС) шире се подручја проблемског карактера. Њихова генеза је дуга и условљена првенствено факторима друштвено-географског карактера. Вишеде- ценијска перцепција руралних подручја као искључиво простора пољопривреде, те мање значајних за савремени развој, нужно се мора мијењати у правцу интегралног приступа њиховој валоризацији, тиме и диверзификацији њихове привреде. Потребе савременог друштва мијењају поглед на рурални простор, његову валоризацију и укупну просторно-функционалну организацију у чему је и шанса потенцијалне ревитализације. Да би рурални простор развио нове функције потребна су инфраструктурна улагања и очуван демографски потенцијал. У акту- елним приликама ова два фактора представљају највеће развојно ограничење. У раду су анализирани географски фактори простора дијела западне БиХ / РС, генеза проблема и заостајања за просјечним националним развојем. У фокусу рада је историјско-географска област Змијања посматрана као дио проблемског подручја. Предлажу се потенцијални приступи валоризацији и просторно-функционалној организацији посматраног простора у циљу његове ревитализације. Рад има теоријски, аналитички и апликативни карактер.

Дизајнирање и картирање представљају веома важан део рада у области развоја картографије. Топограф- ска карта (TK) је графички приказ у размери, који приказује хоризонталне и вертикалне топографске каракте- ристике неког дела Земљине површине, систематски уцртана на равну површину. Користи се за представљање карактеристика земљишта у погледу рељефа, хидрографије, вегетације, насељених места и комуникација и имају најразличитију примену од информисања и оријентације до многих других сфера људског деловања. Најширу примену у Србији има војна топографска карта размера 1:25000 (TK25). Карту чине четири категорије елемената: математички, географски, допунски и елементи оформљења карте. У раду су обрађени ови сегменти, а нарочито физичко-географски и друштвено-географски елементи карте: када се дају, у којој мери, на који начин и визуелно приказани како изгледају на TK наведене размере.

In recent years, the transmission security of image information has become an important research direction in the internet field. In this work, we propose a quantum image chaos encryption scheme based on quantum long-short term memory (QLSTM) network. We find that because the QLSTM network has a complex structure and more parameters, when the QLSTM network is used to improve the Lorenz chaotic sequence, its largest Lyapunov exponent is 2.5465% higher than that of the original sequence and 0.2844% higher than that the sequence improved by the classical long-short term memory (LSTM) network, while its result is closer to 1 and more stable in the 0–1 test. The improved sequence of QLSTM network has better chaotic performance and is predicted more difficultly, which improves the security of single chaotic system encryption. The original image is stored in the form of quantum states by using the NCQI quantum image representation model, and the improved sequence of QLSTM network is used to control the three-level radial diffusion, quantum generalized Arnold transform and quantum W-transform respectively, so that the gray value and pixel position of the quantum image are changed and the final encrypted image is obtained. The encryption scheme proposed in this work obtains the average information entropy of all three channels of RGB of greater than 7.999, the average value of pixel number change rate of 99.6047%, the average value of uniform average change intensity of 33.4613%, the average correlation of 0.0038, etc. In the test of statistical properties, the encryption scheme has higher security than some other traditional methods and can resist the common attacks.

In this paper, we propose a dual-polarization ultra-wideband metasurface with half-reflection and half-transmission based on a double-split-ring (DSR) structure operating in a terahertz (THz) frequency range. The designed metasurface can simultaneously control the circularly polarized (CP) wave and linearly polarized (LP) wave in reflection mode and transmission mode, covering an extensive THz frequency range. The unit-cell architecture of the metasurface consists of a periodic arrangement of the DSR structure made of metal, which is affixed to an ultra-thin dielectric substrate. By manipulating the size and rotation direction of the DSR structure, we achieve full phase coverage of 0–2π of the orthogonally polarized LP wave and CP wave across a frequency span of 0.3–1.2 THz, encompassing transmission and reflection scenarios. The relative bandwidths of the corresponding orthogonal LP wave and CP wave with an average amplitude of 0.45 reach 86% and 120%, respectively. Specifically, through numerical simulations, we demonstrate that the designed metasurface has the ability to achieve THz beam deflection and vortex beam generation while reflecting and transmitting LP wave and CP wave. The proposed dual-polarization ultra-wideband metasurface holds great promise for various applications in the terahertz frequency range. These findings pave the way for the development of flexible and versatile THz devices with expanded functionality, thereby opening up new possibilities for wavefront manipulation in metasurfaces.

In order to study the thermal transport properties of heterogeneous gallium nitride/graphene/silicon carbide interface, the effects of temperature, size and vacancy defects on the thermal conductance of the interface are investigated by non-equilibrium molecular dynamics method, and the effects of changes of phonon state density and phonon participation rate on the thermal conductance of the interface are further analyzed. The results show that the thermal conductance of the interface increases with temperature increasing. The analysis shows that as temperature rises, the lattice vibration intensity, the density of low frequency phonon states, and the number of phonons involved in heat transport all increase. The change of thermal conductance at the interface of single-layer graphene is higher than that of multi-layer graphene. When the structural size of the heat transport direction is changed and the number of layers of gallium nitride and silicon carbide are changed at the same time, the thermal conductance at the interface does not change significantly, and the phonon scattering of the thermal transport at the interface is almost unaffected. However, as the number of graphene interlayers increases from the first layer to the fifth layer, the interface thermal conductance first decreases and then slowly increases. Because of the fourth layer, the participation rate of low frequency phonons decreases, more phonons are localized, and the number of phonons that do not participate in heat transfer increases, and the interfacial thermal conductance reaches a minimum value of 0.024 GW/(m2·K). As the vacancy defect concentration increases, the interfacial thermal conductance first increases gradually and then decreases. The difference is that when the concentration of single vacancy defects is 10%, the interface thermal conductance reaches a maximum value of 0.063 GW/(m2·K). When the concentration of double vacancy defects is 12%, the interfacial thermal conductance reaches a maximum value of 0.065 GW/(m2·K). The analysis shows that more phonons enter into the delocalisation from the local region and more phonons participate in the heat transfer, leading to the increase of the interface thermal conductance. The results are useful in adjusting the thermal transport performance of GaN devices and provide a theoretical basis for designing the devices with heterogeneous interfaces.

Under illumination of a femtosecond laser pulse on the Pt/CoFe/Ta trilayer heterostructure, an impulsive spin current can be generated in the ferromagnetic layer due to the ultrafast demagnetization. The spin current is super-diffusively transported and injected into the neighboring heavy metal layers, and is converted into the transversal charge current due to the spin-orbit coupling, which is named inverse spin Hall effect. The transient charge current on a time scale of sub-picosecond gives rise to the electromagnetic radiation in the far-infrared range to the free space. In this work, we demonstrate two kinds of experiments to investigate the modulation of far-infrared emission by photo-thermal effect, which is due to the thermal energy deposed by light pulses on a short timescales. First, the amplitude of the emitted far-infrared pulse as a function of an applied magnetic field is measured, which shows a far-infrared hysteresis behavior. The coercive field of the sample obtained by far-infrared hysteresis is smaller than that obtained by the M-H hysteresis through vibrating sample magnetometer. In addition, the coercive field decreases with pump laser fluence increasing. Second, the control of spin polarization on an ultrafast timescale in the presence of a small magnetic field applied oppositely to that of the magnetization of the ferromagnetic sample. The amplitude of far-infrared time-domain signal reaches a maximum value at a pump fluence of 1.43 mJ/cm2. For the pump fluence larger than 1.43 mJ/cm2, the far-infrared pulse experiences a phase reversal. After the reversal, a decrease of the laser pump fluence cannot restore the original phase of the far-infrared pulse. The above two experimental results not only elucidate the photothermal effect of femtosecond laser pulses, but also provide a new method for controlling the far-infrared radiation pulses based on ultrafast spintronics. These results demonstrate that far-infrared emission spectroscopy can be used as an ultrafast optical method to investigate magnetic properties, such as the coercive field and anisotropy field of the samples.
