A new physics scenario shows that four-fermion operators of Nambu-Jona-Lasinio (NJL) type have a strong-coupling UV fixed point, where composite fermions

Background
Lymphocytoma cutis (LC) is a benign reactive lymphoproliferative B‐cell process. It has two variants: localized type with solitary lesions and miliarial type with numerous lesions. The ...objective was to investigate the characteristics of LC with emphasis on the miliarial type.
Methods
Retrospective study, patients with clinical and histopathological diagnosis of LC were included. Age, sex, evolution time, affected site, and type of treatment were investigated. In miliarial‐type LC, the histological and immunohistochemical characteristics were also investigated.
Results
In an 18‐year period, there were 102 patients found with LC: 72 (71%) corresponded to females, the median age was 45 years, the median evolution time was 4 months, and the face was the most predominant affected area in 81 (79%) cases. Localized‐type LC corresponded to 88 (86%) cases, and miliarial type in 14 (14%). The most common treatment was surgery, which was used in 32 (31%) patients, all of whom had localized type (P < 0.01). The most frequent treatment for miliarial‐type LC was corticosteroids in five (36%, P = 0.32), the predominant histopathological pattern was nodular in 10 (71%) specimens, and immunohistochemistry was performed in 11 (79%), where all were positive for CD20 with polyclonality to kappa and lambda light chains.
Conclusions
The importance of LC lies in that it can be clinically and histopathologically confused with cutaneous lymphoma and that it is a rare entity, with its miliarial variant being rarer still. This study provides information on the clinical‐histological characteristics of LC and its immunohistochemistry.
Leptoquarks (
LQ
s) are hypothetical particles that appear in various extensions of the Standard Model (SM), that can explain observed differences between SM theory predictions and experimental ...results. The production of these particles has been widely studied at various experiments, most recently at the Large Hadron Collider (LHC), and stringent bounds have been placed on their masses and couplings, assuming the simplest beyond-SM (BSM) hypotheses. However, the limits are significantly weaker for
LQ
models with family non-universal couplings containing enhanced couplings to third-generation fermions. We present a new study on the production of a
LQ
at the LHC, with preferential couplings to third-generation fermions, considering proton-proton collisions at
s
=
13
TeV
and
s
=
13.6
TeV
. Such a hypothesis is well motivated theoretically and it can explain the recent anomalies in the precision measurements of
B
-meson decay rates, specifically the
R
D
(
∗
)
ratios. Under a simplified model where the
LQ
masses and couplings are free parameters, we focus on cases where the
LQ
decays to a
τ
lepton and a
b
quark, and study how the results are affected by different assumptions about chiral currents and interference effects with other BSM processes with the same final states, such as diagrams with a heavy vector boson,
Z
′
. The analysis is performed using machine learning techniques, resulting in an increased discovery reach at the LHC, allowing us to probe new physics phase space which addresses the
B
-meson anomalies, for
LQ
masses up to
5.00
TeV
, for the high luminosity LHC scenario.
The purpose of this study was to examine the impact of immigration legislation on Latino immigrants within the social determinants of health framework to understand the impact of such legislation on ...the immigrant’s health. While the socio-political climate in California is geared towards more pro-integration immigration policies, findings indicate that immigrants still experiences poor treatment in the form of microaggressions, horizontal discrimination, and institutional discrimination. This poor treatment may be an indication of residual anti-immigrant sentiment that remains in the state as well as a spillover effect from the anti-immigrant legislation being passed in neighboring states or national rhetoric. The findings overlap with four domains of the social determinants of health framework including economic stability, education, health and access to care, and social and community context. Implications for practice, policy and research are discussed.
The concept of intermittent computing has been recently proposed, which aims to remove batteries by adding small capacitors or directly powering computing systems from the energy harvesting source, ...retaining computation despite the intermittent nature of the supply. However, certain trivial functions of typical IoT platforms such as performing long-running computation and wireless transmission, or keeping track of time, pose a real challenge in a system with a small amount or total absence of energy storage. This paper proposes a novel framework for time persistency with diverse granularity, based on an hourglass strategy, which includes two small capacitors whose discharge rate is used to calculate the elapsed time from one power cycle to another. The proposed framework was implemented and tested in a real-life IoT system which is used to monitor the temperature of a motorised machine. The experimental results demonstrated an improvement of at least 73.4% in error rate of time measurements, and a minimum reduction of 48.3% in energy consumption against state-of-the-art approaches.
