Irresistible : how cuteness wired our brains and conquered the world
Cuteness is an area where culture and biology get tangled up. Why was cute the aesthetic best able to ride the waves of globalisation, from Edwardian childrens literature to Disney to Hello Kitty and the general explosion of kawaii branded goods? Dale argues that cultural cross-fertilisation in a competitive market drove designers to home in on some of the most powerful psychological triggers we have - the ones that elicit our care and protection.

Search for lepton number violating decays of D s + → h - h 0 e + e
Based on 7.33 fb(-1) of e(+)e(-) collision data collected by the BESIII detector operating at the BEPCII collider at center-of-mass energies from 4.128 to 4.226 GeV, a search for the Majorana neutrino nu(m) is conducted in the lepton-number-violating decays of D-s(+) -> h(-)h(0)e(+)e(+). Here, h(-) represents a K- or pi(-), and h(0) represents a pi(0), K-S(0) or phi. No significant signal is observed, and the upper limits of their branching fractions at the 90% confidence level are determined to be B(D-s(+) -> phi pi(-)e(+)e(+)) < 6.9 x 10(-5), B(D-s(+) -> phi K(-)e(+)e(+)) < 9.9 x 10(-5), B(D-s(+)-> K-S(0)pi(-)e(+)e(+)) < 1.3 x 10(-5), B(D-s(+) -> K(S)(0)K(-)e(+)e(+)) < 2.9 x 10(-5), B(D-s(+) -> pi(-)pi(0)e(+)e(+)) < 2.9 x 10(-5) and B(D-s(+) -> K-pi(0)e(+)e(+)) < 3.4 x 10(-5). The Majorana neutrino is searched for with different mass assumptions within the range [0.20, 0.80] GeV/c(2) in the decay of D-s(+) -> phi e(+)nu(m) with nu(m) -> pi(-)e(+), and the upper limits of the branching fractions at the 90% confidence level are at the level of 10(-5)-10(-2), depending on the mass of the Majorana neutrino.

The power of cute
Cuteness has taken the planet by storm. Global sensations Hello Kitty and Pokâemon, the works of artists Takashi Murakami and Jeff Koons, Heidi the cross-eyed opossum and E.T. - all reflect its gathering power. But what does \"cute\" mean, as a sensibility and style? Why is it so pervasive? Is it all infantile fluff, or is there something more uncanny and even menacing going on - in a lighthearted way? In The Power of Cute, Simon May provides nuanced and surprising answers. We usually see the cute as merely diminutive, harmless, and helpless. May challenges this prevailing perspective, investigating everything from Mickey Mouse to Kim Jong-il to argue that cuteness is not restricted to such sweet qualities but also beguiles us by transforming or distorting them into something of playfully indeterminate power, gender, age, morality, and even species. May grapples with cuteness's dark and unpindownable side - unnerving, artful, knowing, apprehensive - elements that have fascinated since ancient times through mythical figures, especially hybrids like the hermaphrodite and the sphinx. He argues that cuteness is an addictive antidote to today's pressured expectations of knowing our purpose, being in charge, and appearing predictable, transparent, and sincere. Instead, it frivolously expresses the uncertainty that these norms deny: the ineliminable uncertainty of who we are; of how much we can control and know; of who, in our relations with others, really has power; indeed, of the very value and purpose of power. The Power of Cute delves into a phenomenon that speaks with strange force to our age.

Study of the semileptonic decay D 0 â (K)over-bar 0 Ï - e + Îœe
We report an improved study of the semileptonic decay D-0 -> (K) over bar (0)pi(-)e(+)nu(e) based on a sample of 7.9 fb(-1) of e(+) e(-) annihilation data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII collider. The branching fraction of this decay is measured to be B(D-0 -> (K) over bar (0)pi(-)e(+)nu(e)) = (1.444 +/- 0.022(stat) +/- 0.024(syst))%, which is the most precise to date, where the first uncertainty is statistical and the second is systematic. Based on investigation of the decay dynamics, we find that the decay is dominated by the K*(892)(-) component and present an improved measurement of its branching fraction to be B(D-0 -> K*(892)(-)e(+)nu(e)) = (2.039 +/- 0.032(stat) +/- 0.034(syst))%. We also determine the ratios of the hadronic form factors for the K*(892)- e(+) nu(e) decay to be rV = V (0)/A(1)(0) = 1.48 +/- 0.05(stat) +/- 0.02(syst) and r(2) = A(2)(0)/A1(0) = 0.70 +/- 0.04(stat) +/- 0.02(syst), where V (0) is the vector form factor and A(1,2)(0) are the axial form factors. In addition, the (K) over bar (0)pi(-) S-wave component is found to account for (5.87 +/- 0.32(stat) +/- 0.16(syst))% of the total decay rate, corresponding to a branching fraction of B[D-0 ->((K) over bar (0)pi(-)) S-wave e(+)nu(e)] = (0.085 +/- 0.005(stat) +/- 0.003(syst))%.

Polish your poise with Madame Chic : lessons in everyday elegance
\"Madame Chic embodied poise, and not just with the good posture, stylish attire, and natural manners that made her extraordinarily elegant. She also demonstrated steady assuredness and graceful calm in everything she did--from interacting with her family and receiving guests at home to presenting herself in public. Jennifer L. Scott passes on the lessons she learned as well as some of her own hard-won wisdom, addressing topics such as proper attire at social events, good grooming, communication skills, hospitality and being a good guest, our interactions with neighbors and strangers, role models, self-discipline, and self-image\"-- Provided by publisher.

We search for the radiative decays D+ -> gamma rho(+) and D+ -> gamma K*+ using 20.3 fb(-1) of e(+)e(-) annihilation data collected at the center-of-mass energy root s = 3.773 GeV by the BESIII detector operating at the BEPCII collider. No significant signals are observed, and the upper limits on the branching fractions of D+-> gamma rho(+) and D+-> gamma K*+ at 90% confidence level are set to be 1.3 x 10(-5) and 1.8 x 10(-5), respectively.

Measurements of K S 0 - K L 0 asymmetries in the decays Λ c + → pK L,S 0 , pK L,S 0 π + π - and pK L,S 0 π 0
Using e(+)e(-) annihilation data sets corresponding to an integrated luminosity of 4.5 fb(-1), collected with the BESIII detector at center-of-mass energies between 4.600 and 4.699 GeV, we report the first measurements of the absolute branching fractions B(Lambda(+)(c)-> pK(L)(0) = (1.67 +/- 0.06 +/- 0.04)%, B(Lambda(+)(c)-> pK(L)(0) pi(+)pi(-) = (1.69 +/- 0.10 +/- 0.05)%, and B(Lambda(+)(c)-> pK(L)(0)pi(0) = (2.02 +/- 0.13 +/- 0.05)%, where the first uncertainties are statistical and the second systematic. Combining with the known branching fractions of Lambda(+)(c)-> pK(S)(0), Lambda(+)(c)-> pK(S)(0) pi(+)pi(-), and Lambda(+)(c)-> pK(S)(0)pi(0), we present the first measurements of the K-S(0)-K-L(0) asymmetries R(Lambda K-+(c)S,L(0) X) = B(Lambda(+)(c) -> (KSX)-X-0-B (Lambda(+)(c)-> K-L(0) X/B(Lambda(+)(c)->(KSX)-X-0)+B(Lambda(+)(c)->(KLX)-X-0) in charmed baryon decays: R(Lambda(+)(c)pK(S,L)(0)) = -0.025 +/- 0.031, R(Lambda(+)(c)pK(S,L)(0) pi(+)pi(-)) = -0.027 +/- 0.048 and R(Lambda(+)(c)pK(S,L)(0)pi(0) = -0.015 +/- 0.046. No significant asymmetries with statistical significance are observed.

STCF conceptual design report (Volume 1): Physics & detector
The super τ-charm facility (STCF) is an electron−positron collider proposed by the Chinese particle physics community. It is designed to operate in a center-of-mass energy range from 2 to 7 GeV with a peak luminosity of 0.5 × 10 35 cm −2·s −1 or higher. The STCF will produce a data sample about a factor of 100 larger than that of the present τ-charm factory - the BEPCII, providing a unique platform for exploring the asymmetry of matter-antimatter (charge-parity violation), in-depth studies of the internal structure of hadrons and the nature of non-perturbative strong interactions, as well as searching for exotic hadrons and physics beyond the Standard Model. The STCF project in China is under development with an extensive R&D program. This document presents the physics opportunities at the STCF, describes conceptual designs of the STCF detector system, and discusses future plans for detector R&D and physics case studies.

Using proton-proton collision data, corresponding to an integrated luminosity of 9 fb −1 , collected with the LHCb detector between 2011 and 2018, a new narrow charmonium state, the X(3842) resonance, is observed in the decay modes$$ \\mathrm{X}(3842)\\to {D}^0{\\overline{D}}^0 $$X 3842 → D 0 D ¯ 0 and X(3842) → D + D − .
