Unifying approaches: derivation of Balitsky hierarchy from the Lipatov effective action

We consider a derivation of the hierarchy of correlators of ordered exponentials directly from the Lipatov’s effective action (Lipatov in Nucl Phys B 452:369, 1995; Phys Rep 286:131, 1997; Subnucl Ser 49:131, 2013; Int J Mod Phys Conf Ser 39: 1560082, 2015; Int J Mod Phys A 31(28/29):1645011, 2016; EPJ Web Conf 125: 01010, 2016) formulated in terms of interacting ordered exponentials (Bondarenko and Zubkov in Eur Phys J C 78(8), 617 2018; Bondarenko et al. in Eur Phys J C 81(7):61, 2021). The derivation of the Balitsky equation (Balitsky in Nucl Phys B 463:99, 1996; Phys Rev D 60:014020, 1999; At the frontier of particle physics, vol. 2, p. 1237–1342; Nucl Phys B 629:290, 2002; Phys Rev D 72:074027, 2005) from the hierarchy is discussed as well as the way the sub-leading eikonal corrections to the Balitsky equation arise from the transverse field contribution and sub-leading eikonal corrections to the quark propagator. We outline other possible applications of the proposed calculation scheme.

El presente estudio evalúa el efecto de una intervención adaptada del Programa Inteligencia Emocional Plena (PINEP) en adultos que han sufrido la pérdida de un ser querido. La intervención tiene una duración de doce sesiones, de dos horas y media por semana. La muestra está compuesta por 17 adultos de un rango de edad de entre 26 y 71 años (M = 50.59; SD = 14.44). Los participantes que completaron la intervención, muestran una mayor tolerancia al malestar desarrollando habilidades en mindfulness [t(16) = 4.17, d = 1.04, p ≤ .001] y una disminución en ansiedad estado [t(16) = -2.94, d = .72, p = .005], ansiedad rasgo [t(16) = -3.48, d = .78, p ≤ .001] y depresión [t(16) = -3.18, d = .66, p= .003]

Perbandingan Dampak El Nino Kuat 2015/16 Dan 1997/98 Terhadap Curah Hujan Di Provinsi Bali - Indonesia

Penelitian ini bertujuan untuk mengetahui perbandingan fenomena El Nino 2015/16 dan 1997/98 dari segi indeks dan dampak keduanya terhadap curah hujan di Provinsi Bali - Indonesia. Metode analisis yang digunakan berupa metode Korelasi Pearson dan statistik deskriptif terhadap data Indeks Nino 3.4 yang dikonversi menjadi Oceanic Nino Index (ONI) dan data curah hujan bulanan di 22 titik penakar hujan Provinsi Bali. Hasil penelitian menunjukan El Nino 2015/16 (indeks tertinggi 2.37) sedikit lebih kuat daripada El Nino 1997/98 (indeks tertinggi 2.33). Berdasarkan siklus hidupnya, El Nino 2015/16 lebih lama bertahan dibandingkan dengan El Nino 1997/98. Hubungan antara El Nino dengan curah hujan Bali diketahui lebih kuat pada periode September-Oktober-Nopember (SON) dibandingkan dengan periode Desember–Januari–Februari (DJF). Kemudian setelah dilakukan perbandingan antara kedua kejadian El Nino Kuat tersebut, ternyata dampak penurunan curah hujan di Provinsi Bali saat El Nino Kuat 2015/16 (-6% s/d -46%) tidak separah dampak penurunan curah hujan saat fenomena El Nino Kuat 1997/98 (-18% s/d -72%)

How Do ImPACT Quick Test Scores Compare with ImPACT Online Scores in Non-Concussed Adolescent Athletes?

Objective To compare neurocognitive scores between the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) Quick Test (QT) and Online Versions in non-concussed high school athletes. Methods A sample of 47 high school athletes completed the ImPACT Online Version pre-season and the ImPACT QT approximately 3 months later. Paired sample t-tests and Pearson’s correlations examined differences and relationships between the ImPACT batteries. Results The ImPACT QT scores were significantly higher for performance on the Three Letters: Average Counted (p < .001, d = .88), Three Letters: Average Counted Correctly (p < .001, d = .80), and Symbol Match: Correct RT Visible (p < .001, d = .72), and Symbol Match: Correct RT Hidden (p = .002, d = .50) subtests. There were significant relationships for Three Letters: Average Counted (r = .85, p < .001), Three Letters: Average Counted Correctly (r = .82, p < .001), and Symbol Match: Total Correct Hidden (r = .40, p = .006) subtests. Conclusions Post-injury evaluation data using ImPACT QT should be compared to normative referenced data, and not to pre-season data from the ImPACT Online Version.

Perfil imuno-hematológico das gestantes aloimunizadas em instituto federal entre 2014 e 2019

Introdução: A aloimunização é a formação de anticorpos maternos contra antígenos presentes no sangue fetal. Dependendo da capacidade de atravessarem a placenta, antigenicidade e concentração de anticorpos envolvidos, pode haver desenvolvimento de doença hemolítica perinatal. A profilaxia de aloimunização com imunoglobulina anti-D é extremamente eficaz em reduzir a morbimortalidade da doença, uma vez que esse anticorpo é o principal responsável por causar hemólise. Por outro lado, o uso dessa profilaxia tem levado a aumento proporcional de casos de doença por anticorpo não-D. Objetivo: Descrever o perfil imuno-hematológico das gestantes aloimunizadas acompanhadas em centro de referência entre 2014 e 2019. Material e Métodos: Foi realizada revisão de prontuários, analisando o grupo sanguíneo (GS), o fator Rh e o tipo de anticorpo contra hemácia. Além disso, foi realizada revisão da literatura acessada nas bases de dados PubMed e Uptodate. Resultados: Entre 2014 e 2019, foram acompanhadas 416 gestantes aloimunizadas nessa instituição. Entre elas, o GS mais comum foi A (42,1%), seguido de O (38,5%), B (14,2%) e AB (4,6%). As pacientes eram predominantemente Rh negativo (81,5%), enquanto o restante era Rh positivo (18,5%). A titulação do Coombs indireto variou entre 1:1 e 1:4096, com a maioria das gestantes (15%) com titulação de 1:16. Quanto ao tipo de anticorpo, a maior prevalência foi de anti-D (72%), seguido, respectivamente, de anti-M (7%), anti-K, anti-E, anti-Lews, anti-C e anti-c. Em 87% dos casos, houve identificação de apenas um anticorpo; em 11% dos casos foram identificados dois anticorpos; e em 2%, três ou mais anticorpos. Quanto à associação do anti-D com outros anticorpos, em 9% dos casos o segundo anticorpo identificado foi o anti-C; em 2%, o anti-E; e em 1%, o anti-K, seguidos do anti-e e do anti-S, com 0,5% cada. Discussão: Apesar da existência da profilaxia para aloimunização para anti-D, analisando o perfil imuno-hematológico das gestantes aloimunizadas na instituição, observa-se o predomínio absoluto de anticorpos anti-D. A prevenção da doença hemolítica perinatal por meio da administração de imunoglobulina anti-D é considerada extremamente eficaz, com taxa de sucesso de aproximadamente 99%. A profilaxia com imunoglobulina anti-D está disponível desde 1968 e é capaz de reduzir a taxa de aloimunização de 13‒16% para 0,5‒1,8%. Segundo a literatura, no mundo todo, aproximadamente 50% das mulheres que deveriam receber a profilaxia não a recebem, o que leva à exposição de milhares de fetos e neonatos à elevada morbimortalidade da doença. Conclusão: A doença hemolítica perinatal é potencialmente grave e sua forma mais comum é prevenível por meio da administração da imunoglobulina anti-D. O predomínio da aloimunização pelo anti-D na população estudada traduz a deficiência na implementação da profilaxia e torna essa doença um grande desafio à saúde pública.

Electron-Impact Dissociation of Vibrationally-Excited Molecular Hydrogen into Neutral Fragments

We present convergent close-coupling (CCC) calculations of electron-impact dissociation of vibrationally-excited molecular hydrogen into neutral fragments. This work follows from our previous results for dissociation of molecular hydrogen in the ground vibrational level [Scarlett et al., Eur. Phys. J. D 72, 34 (2018)], which were obtained from calculations performed in a spherical coordinate system. The present calculations, performed utilizing a spheroidal formulation of the molecular CCC method, reproduce the previous dissociation cross sections for the ground vibrational level, while allowing the extension to scattering on excited levels.

Indizierte Prävention internalisierender Störungen

Die vorliegende Studie überprüft die Wirksamkeit eines kognitiv-verhaltenstherapeutischen Präventionsprogramms für Kinder mit internalisierenden Symptomen. Eine modifizierte Version der deutschen Bearbeitung des australischen Programms FRIENDS wurde im indizierten Präventionskontext angewendet und unter Verwendung eines Wartelistendesigns mit Eigenkontrollgruppe evaluiert. 81 Kinder (42 Jungen, 39 Mädchen) im Alter von acht bis 12 Jahren nahmen teil. Sowohl das Elternurteil (CBCL), als auch das Selbsturteil der Kinder (SCAS, DIKJ) wurden zur Wirksamkeitsüberprüfung herangezogen. Die Datenerhebungen erfolgten zu drei Zeitpunkten (drei Monate vor Beginn sowie unmittelbar vor und nach der Intervention). Die Ergebnisse sprechen für die Effektivität des Programms; die internalisierenden Symptome der Kinder reduzierten sich während der Intervention signifikant stärker als während der Wartezeit. Mittlere Effektstärken zeigten sich sowohl aus Elternsicht (d = .72), als auch aus Kindersicht (d = .55).
