Studies on gluon evolution and geometrical scaling in kinematic constrained unitarized BFKL equation: application to high-precision HERA DIS data

We suggest a modified form of a unitarized BFKL equation imposing the so-called kinematic constraint on the gluon evolution in multi-Regge kinematics. The underlying nonlinear effects on the gluon evolution are investigated by solving the unitarized BFKL equation analytically. We obtain an equation of the critical boundary between dilute and dense partonic system, following a new differential geometric approach and sketch a phenomenological insight on geometrical scaling. Later we illustrate the phenomenological implication of our solution for unintegrated gluon distribution $f(x,k_T^2)$ towards exploring high precision HERA DIS data by theoretical prediction of proton structure functions ($F_2$ and $F_L$) as well as double differential reduced cross section $(\sigma_r)$. The validity of our theory in the low $Q^2$ transition region is established by studying virtual photon-proton cross section in light of HERA data

Inter-limb jump asymmetries and their association with sport-specific performance in young male and female swimmers

This study aimed to examine inter-limb jump asymmetries and their association with sport-specific performance in young swimmers. Thirty-eight (male, n = 19; female, n = 19) regional/national level young swimmers (age: 12.3 ± 1.2 years; height: 159.6 ± 8.2 cm; body mass: 52.5 ± 9.2 kg) participated in this study. Inter-limb asymmetries were assessed for single-leg countermovement jump (SLCMJ) and single-leg standing long jump (SLSLJ). Sport-specific performance was evaluated using front crawl (i.e., 50 m and 25 m) and front crawl kick (i.e., 50 m and 25 m). The kappa coefficient revealed a “slight” level of agreement (Κ = 0.156, 0.184, and 0.197 for female, male, and all, respectively) between the direction of asymmetry for SLCMJ and SLSLJ, indicating that asymmetries rarely favored the same limb during both tests. A paired sample t-test showed a significant difference (p = 0.025) between asymmetry scores obtained in SLCMJ and SLSLJ. No significant difference was found in asymmetry scores between males and females (p = 0.099 to 0.977). Additionally, no association between asymmetry scores and sport-specific performance was observed (p > 0.05). Our findings highlight the independent nature of inter-limb asymmetries derived from SLCMJ and SLSLJ among young male and female swimmers. Further, our results suggest no association between jumping asymmetries and sport-specific performance

Seizing opportunities to diversify conservation

Conservation Letters published by Wiley Periodicals, Inc. This article identifies, and offers several ways to address, a serious, persistent issue in conservation: low levels of diversity in thought and action. We first describe the lack of diversity and highlight the continued separation of the environmental conservation and environmental justice movements. We then offer—based on previous research and our collective experience—two suggestions for how to increase inclusivity (a step farther than increasing diversity) in holistic ways. We suggest that embracing narrative, including historical narrative that can be profound and painful, may be essential to addressing this deeply rooted issue. We also suggest the need to redefine “environment” to more closely align with the diversity of perspectives that different people and disciplines bring to the topic. We support our suggestions with selected data from empirical research and provide examples of initiatives that embody them

A two years study of histopathological spectrum of skin adnexal tumors in a tertiary care centre of Southern Assam, India

Background: Skin adnexal tumors (SAT) encompass a wide spectrum of benign and malignant tumors that differentiate toward one or more adnexal structures found in normal skin. Overall incidence of SATs is low yet they can be challenging to diagnose. Our study aims at analysis of histopathological spectrum of various SATs according to age, sex and anatomic locations along with histopathological features.Methods: It was a retrospective cross-sectional study conducted over a period of 2 years from June 2017 to May 2019. All cases were retrieved from department registries and analyzed.Results: Out of the total 4013 biopsies, 25 cases were diagnosed as SATs comprising 44% of tumors with eccrine sweat gland differentiation followed by tumors showing hair follicle differentiation (32%), sebaceous differentiation (16%) and apocrine gland differentiation (8%). The age ranged from 4 years to 68 years and male: female ratio was 1:1.5. Most of the tumors were benign (84%) while only 16% were malignant. Pilomatricoma (19%) was the most common benign tumor while sebaceous carcinoma (75%) was the most common malignant tumor.Conclusions: Skin adnexal tumors are relatively rare neoplasm. Malignant cases are less common than benign ones. Histopathology is quite essential for diagnostic point of view

Micropropagation of Curcuma amada (Roxb.)

Rhizome explants of Curcuma amada (Roxb.) produced shoots and roots simultaneously when cultured in B6 medium containing NAA and BAP. This technique would be suitable for field propagation and conservation. &nbsp
